Question

Find the measure of each angle of a parallelogram, if larger angle is 30c less than twicethe smaller angle.

Answer 1

The equation satisfies is x = 2y - 30

x = larger angle

y = smaller angle

x + 2y - 30° = 180°

2y - 30° + 2y - 30° = 180°

4y = (180 + 60)°

y = 60°


x = 2(60°) - 30°

x = 90°

Answer 2

the equation formed=2y-30
y=larger angle
x=smalller angle
x+2y-30°=180°
2y-30°+2y-30°=180°
4y-60°=180°
4y=180+60°
y=60°
x=2*60-30
x=90°
