Question

find the measure of an angle which is 30° more than one half of its complement​

Answer 1

Answer:

complementary angle adds up to 180.

x +( x + 30) = 180

2x + 30 = 180

2x = 180 - 30

2x = 150

x = 150/2

x = 75

Answer 2

Let the complement of the angel be x°

Then x+x+30 =180

2x =180-30

=150

X=150÷2

=75°

Then,required angles are

X=75. And

X+30=75+30

=105°
