A. 63.1°
<u>Step-by-step explanation:</u>
Whatever it may be reflection, rotation or translation, the angle or size of the triangle will not change.
As we know that the sum of angles in a triangle is 180°.
In ΔX'Y'Z', ∠X' + ∠Y' + ∠Z' = 180°
53.8° + 63.1° + ∠Z' = 180°
116.9° + ∠Z' = 180°
∠Z'= 180° - 116.9°
= 63.1°
Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
