Answer:
Step-by-step explanation:
1. 670
2. 25500
3. 140.55
4. 54
5. 159.5
If the triangles ABC and A'B'C' are similar, then
angle A = angle A'
8x-10 = 6x+10
8x-6x = 10+10
2x = 20
x = 20/2
x = 10
So angle A is
angle A = 8x-10
angle A = 8*10-10
angle A = 80-10
angle A = 70
making that the measure of angle A' as well
This is why the answer is choice A
Your answer is Graph A.
Hope this helps :)!!!
