Question

TWO complementary angles differ by 30° then Find the angles​

Answer 1

Answer:

Step-by-step explanation:

Let one angle be x

Other = x + 30

So, x + x+ 30 = 90 (as sum of complementary angles is 90)

2x = 90 -30

2x = 60

x = 30

One angle = 30

Other angle = 30 + 30 = 60

Answer 2

Let the bigger angle = x

Let the smaller angle = x - 30°

According to question :

They are complementary angles . So

Bigger Angle + Smaller Angle = 90°

x + ( x - 30) = 90°

2x - 30 = 90

2x = 90 + 30

2x = 120

x = 120 / 2

x = 60°

The Bigger Angle = x = 60°

The Smaller Angle = x - 30

= 60 - 30 = 30°
