Solve for x. Then multiply it by 2.

x + 2x = 90

x + 2x = 90

so you would divide 2x on both sides, it would then look like this:

x + 2x = 90
-- --
2x 2x

x = 45

so you would then assume that both angles measurements are 45 degrees each, which would equal to 90 degrees, because a complementary angle measures 90 degrees. hope this helps!

Jen -- you did not read the problem carefully!

One of the angles is twice the other.

Also x + 2x does not equal 2x.

x+2x=90°

3x=90° Divide both sides with 3

x=30°

The larger angle has a measure of:

2x=60°
