Answer:
B is a solution, A and C are not
Step-by-step explanation:
Answer:
- Scale factor = 1/2 and x = 18
Step-by-step explanation:
<u>Given:</u>
- ΔABC ~ ΔDEF
- AB = 36. BC = 30
- DE = x, EF = 15
- m∠B = m∠E = 72°
<u>Corresponding sides are:</u>
<u>Corresponding sides have same ratio:</u>
- AB/DE = BC/EF
- 36/x = 30/15
- x = 36/2
- x = 18
<u>The scale factor is:</u>
