Answer:

The ratio of 3:6 means the 180 degrees has been split into 3+6 = 9 parts. One angle is 3 parts, so it = 3*20 = 60 degrees. The other is 6 parts, so it = 6*20 = 120 degrees.

Step-by-step explanation:

The measure of the larger angle is 60°

What are complementary angles?

"Two angles are complementary angles when their sum is 90°"

What is ratio?

"It is the comparison of two quantities of the same type."

For given example,

the ratio two complementary angles is 3:6

This means these complementary angles are 3x, 6x , where x represents the common angle of the ratio 3:6

Since the sum of the complementary angles is 90°

⇒ 3x + 6x = 90

⇒ 9x = 90

⇒ x = 90/10

⇒ x = 10°

So, the measure of the complementary angles would be,

⇒ 3x = 3 × 10°

⇒ 3x = 30°

And, 6x = 6 × 10°

⇒ 6x = 60°

Therefore, the measure of the larger angle is 60°
