Answer:
-5y=-10x+100
y=2x-20
6y=-3x-7
y=-1/2x-7/6
Perpendicular because the slopes are opposite
Your answer would be 76.1
Option B, 34 degrees. The angles 'x' and '34' are alternate interior angles, meaning that they're congruent.
Given:
square based pyramid = 3.5 cm base
side length = 7 cm
Base Area = (3.5cm)² = 12.25cm²
Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
S.A = 61.25 cm²
