plz ans!!!!!!!!!4th ques​

Answer 1

Answer:complementary means addition is 60 thus the angles are 60 and 30

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Let the complement angle be x.

The required angle is (y)=90-x-----i

Also from question,

Y =30+ 0.5(x)

Y =30+(x/2)

X/2=y-30

X=2y-60---------ii

There fore,

Substituting ii in i

Y=90-(2y-60)

Y=90-2y+60

Y =150-2y

3y=150

Y=150/3=50

Therefore the required angle is 50
