Answer:
87°
Step-by-step explanation:
if an angle is complementary that means that equals 90°.
and we know one part of the angles, so then we take 90° - 3° and we get 87°.
Answer:
The measure of its complementary angle is 87°
Step-by-step explanation:
We know this because the sum of two complementary angles is always equal to 90°, so:
90 - 3 = 87
Therefore, your final answer will be 87°

Television sizes are described by the length of their diagonal measure. What would be the listed size of the TV shown? (to the nearest whole inch)
1,424
32
38
20
Answer:
38 inches
Step-by-step explanation:
since we are finding the diagonal we are going to use the equation a^2+b^2=c^2
so if we do substitution we would have 32^2+20^2=C^2
32^2= 1024
20^2= 400
so,
1024 + 400 = C^2
1424 = C^2
to get rid of the C^2 we have to take the square root of it. But whatever we do on one side of the equation we have to do on the other side so,
C = sqrt(1424)
C = 37.73
C = 38 inches
In the diagram, line x is parallel to line y,m21= 65°, and m27 = 55°. Stuart says that m212 = 60°. His reasoning is shown. Step 1: mZ8 = 60°, because m21+ m27 +m28 = 180º. Step 2:28 212, because 28 and 212 are corresponding angles. Step 3: So, mZ12 = 60° Use the drop-down menus to explain whether or not Stuart is correct.
Answer:
180, same side interior, 120, incorrect
Step-by-step explanation:
Seeing that the other person failed to answer the question at all and made a worthless topic answer. I went ahead and solved it.
So all you have to know that sets stuart wrong is that angle 12 is not 69 degrees. So the dropdowns as follows. Angle 1, 7 and 8 make one triangle and have equal degrees. So 180 equals a whole triangle. Angle 12 and 8 are on the same side and inside the triangle. (Remember 1,7,8? well divide 180 by 3 and u get angle 8 being 60. Same as angle 7. The interior trapezoid will be 60+60+120+120=360.) Angle 12= 120 thus Stuart is wrong.
The reasoning that may be used for finding the measure of m∠12, is the
same side interior angles theorem.
The correct options using the drop-down menu are;
The sum of ∠1, ∠7, and ∠8 is 180°∠8 and ∠12 are same side interior anglesThe measure of ∠12 must be = 120°Stuart is not correctReasons:
Given parameters;
Line x ║ line y
m∠1 = 65°, m∠7 = 55°
m∠12 = 60°
Stuart states ∠12 = 60°
The reasoning is presented as follows;
Step 1: m∠8 = 60°, because m∠1 + m∠7 + m∠8 = 180°
Step 2: ∠8 ≅ ∠12, because ∠8 and ∠12 are corresponding angles
Step 3: So, m∠12 = 60°
Using the drop-down menu, we have;
The sum of ∠1, ∠7, and ∠8 is 180° (Sum of angles in the triangle)
∠8 and ∠12 are same side interior angles (by definition)
Same side interior angles are supplementary, therefore;
∠8 +∠12 = 180°
∠12 = 180° - ∠8
Which gives;
The measure of ∠12 must be 180° - ∠8 = 180° - 60° = 120°
The measure of ∠12 must be = 120°
Stuart is not correct

A statue at the park needs to be moved. Workers need to move it 7 yards north and 20
yards west. Which of the following represents the job they must do?
a) ( − 20, + 7)
b) ( + 7, + 20)
c) ( + 20, + 7)
d) ( − 7, − 20)
Answer:
the answer is a) (-20, +7)
Step-by-step explanation:
This because by moving the statue north, they are moving it up, and bye moving west they move it to the left. You can tell what is positive and negative by visualizing a graph. Going north is like moving up the y-axis, so you add 7 to the y coordinates. And moving it west would be like moving the statue towards the negative side of the x-axis, thus subtracting 20.
Serena wants to create snack bags for a trip she is going on. She has 6 granola bars and 10 pieces of dried fruit. If the snack bags should be identified without any food leftover, what is the greatest number of snack bags Serena can make?
Answer:
2
Step-by-step explanation:
Given the question :
Serena wants to create snack bags for a trip she is going on. She has 6 granola bars and 10 pieces of dried fruit. If the snack bags should be identified without any food leftover, what is the greatest number of snack bags Serena can make?
Number of granolas = 6
Number of dried fruits = 10
Since the snackbag is to be designed in such a way that there should be no food leftover, the greatest number of snack bags Serena can make could be obtained by getting the highest common factor of (6 and 10)
____6____10
2___3____5
Here, the highest common factor of 6 and 10 is 2
Hence, the greatest number of snack bags she can make is 2.

A bag contains 39 colored marbles. There are 6 blue marbles, 14 red marbles, 8 yellow marbles, and 11 clear marbles. What is the ratio of blue to red marbles?
Answer:
3 to 7
Step-by-step explanation:
blue to red
6 to 14
Divide each side by 2
6/2 to 14/2
3 to 7
Answer:
The ratio would be 6:10 or 6/10 ( 3/5) or 0.6.
Step-by-step explanation:
Why? A ratio is comparing two numbers with a fraction, colon or decimal or percent.
Well there are 6 blue marbles out of the 35 colored marbles. And there are 10 clear marbles.
The question is asking for a blue/clear. It is easy to get confused and put clear/blue. So that is why 6:10 is the ratio.

Mary's car can go 24 miles on one gallon of gasoline. However , her gas mileage can vary by 2 miles per gallon depending on where she drives . Write an absolute value equation that you can use to find the minimum and maximum gas mileage.
Answer: | x -24 |=2
Step-by-step explanation:
Given: Mary's car can go 24 miles on one gallon of gasoline.
her gas mileage can vary by 2 miles per gallon depending on where she drives .
i.e. either 2 miles added or subtracted in the gas mileage.
i.e. -2< Gas milegae -24 <2
⇒ | Gas milegae -24 |=2
Let x represents the gas mileage.
Then, | x -24 |=2 is the required absolute value equation that you can use to find the minimum and maximum gas mileage.
