The supplement of an angle is 50 less than 3 times its complement, find the measure of the angle
Lelechka [254]

Answer:

20^{\circ}.

Step-by-step explanation:

Two angles are supplements of one another if their sum is 180^{\circ}.

Two angles are complements of one another if their sum is 90^{\circ}.

Let x^{\circ} be the measure of the angle in question.

The supplement of this angle would be (180 - x)^{\circ}.

The complement of this angle would be (90 - x)^{\circ}.

According to the question:

(180 - x) + 50 = 3\, (90 - x).

Solve this equation for x:

x = 20.

Thus, this angle would measure should 20^{\circ}.

The supplement of this angle would measure (180 - 20)^{\circ} = 160^{\circ}. The complement of this angle would measure (90 - 20)^{\circ} = 70^{\circ}.

Three times the complement of this angle would be 3 \times 70^{\circ} = 210^{\circ}, which is indeed 50^{\circ} greater than the supplement of this angle.
