Question

Find the angle which is four times its complement is 10° less than twice its complement

Answer 1

Step-by-step explanation:

If we call the angle a, then...

 4(90 - a) = 2(180 - a) - 10

360 - 4a = 360 - 2a - 10

2a = 10

a = 5 deg

Answer 2

Step-by-step explanation:

Here's the answer to your question.

Let the angle be = x

= Its complement = 90-x and its supplement = 180-x

According to the question, 7(90-x) = 3(180-x) -10

= 630 - 7x = 540- 3x -10

= 630-7x = 530-3x

= 630-530 = -3x+7x (Transposing -7x and 530)

= 100 = 4x

= x= 25
