If 3 times the supplement of an angle is subtracted from 7 times the complement of the angle, the answer is the same as that obtained from trisecting a right angle. What is the supplement of this angle?

Answer 1

150 degrees.

Let the angle be x . according to given conditions, 3(180- x ) - 7(90- x ) = #90/3#

540- 3 x - 630 +7 x = 30

4 x - 90 = 30

4 x = 30+90

4 x = 120

x = #120/4#

x = 30

supplement of angle = 180 - 30 = 150 degrees

Answer 2

Let x be the angle.

Given: (7(90 - x) - 3(180 - x) = 3(30))

Solving for x:

(630 - 7x - 540 + 3x = 90)

(90 - 4x = 90)

(-4x = 0)

(x = 0^\circ)

Supplement of the angle = (180 - x = 180 - 0 = 180^\circ)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
