Question

Two angles are complementary the larger angle is 30less than twice the measure of the smaller angle find the measure of each angle.

Sonia

Answer 1

30 degree + Angle x + Angle y = 360 degree

2y-30+y=90

3y=120

y=120

Y=40

X=2y-30

X=2(40)-30

X=50

Answer 2

let the angles be x and y

According to question,

x=2y-30

Also,x+y=90

2y-30+y=90

3y=120

y=40

Therefore, x=2(40)-30

=50
