Question

An angle is 30° less than two times its complement. Find the angle.

Answer 1

Step-by-step explanation:

Let x be the unknown angle of the condition.

Then the complementary angle is 90°-x.

According to the condition,

90 - x = 2x - 30.

Solve it:

90 + 30 = 2x + x,

3x = 120.

Thus one angle is 40°. The other angle is 50

Answer 2

Answer:

one angle is 40°. The other angle is 50

Step-by-step explanation:

Let x be the unknown angle of the condition. Then the complementary angle is 90°-x.

According to the condition,

90 x 2x - 30.

Solve it:

90+30 2x + x,

3x = 120.

Thus one angle is 40°. The other angle is 50
