Question

an angle is 30 less than twice its Complement find the angle​

Answer 1

Answer:

complementary angles are those who add up to 90

so

an angle is twice less than its complement

x+30=90

x=90-30

x=60

check

30*2=60

hope it helps you

Answer 2

Answer:

The complement of an angle is 30 less than twice angle. Find the larger angle.

-----------------------------------------------------------------------------

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. The larger angle is 50°.
