Question

) (a + 30)° and (2a)° are the measures of two complementary angles. What is the measure of each angle?

Answer 1

Answer:

a+30°=90

a=60°

2a°=90

a=45°

Answer 2

Answer:

Two measures are given

(a+30)degree and (2a)degree

First we have to find a

we know complementary angles =90 degree

so,a+30+2a=90degree

3a+30=90degree

3a=90-30degree

3a=60degree

a=60/3

a=20

Now,

1st measure=(a+30) = 20+30=50degree

2nd measure=(2a) = 2x20=40degree

So, your answer is 50 and 40 degree
