Question

A,b are complementary.angle a =1/7of angle b. Find angle b

Answer 1

Answer:

Step-by-step explanation:given B=7A

We know that sum of complementary angles is 90°.

Acc to question

A+B=90°

so 7B+B=90°

B=90°/8

so B=11° degree 15'minutes

Answer 2

Answer:

Step-by-step explanation:

A & B are complementary angles

We now that the sum of complementary angls are 90 degrees

Given angle A = 1/7 of angle B, that's why

A = 1/7 * B

For complementary angles,

A + B = 90°

B/7 + B = 90°

(B + 7B ) / 7 = 90°

B + 7B = 90* 7

8B = 630

B = 630 / 8

B = 78 degrees 75 minutes
