Question

Find the value of each variable.

X= 75° and y=78°
X = 71.5º and y = 71.5°
X = 78° and y = 65°
X = 102° and y= 115°

Answer 1

Third option

Explanation:

1. Estimate closest answer based on four given options visually

90˚ < x˚ < 75˚

y˚ ≠ x˚ , y˚ < 75˚

2. Angle calculations

360-115-102-x-y=0

Plug in each equation and you get

360-115-102-78-65=0

X = 78˚ and y = 65˚
