Question

20. Olivia translated triangle DEF 4 units vertically to form triangle GHJ.

If Olivia performed the translation correctly, what is the measure of angle H?
O 17.5°
O 43.0°
O 32.5°
O 28.0°

Answer 1

Explanation:

m∠E = m∠H

( 3x - 20 )° = ( x + 15 )°

3x - 20 = x + 15

3x - x = 15 + 20

2x = 35

x = 17.5

m∠H = 3(17.5) - 20 = 32.5 °
