Two angles are complementary. One of the angles is twice the other.
The larger angle has a measure of

Solve for x. Then multiply it by 2.
x + 2x = 90

math  Jen, Saturday, July 23, 2011 at 6:45pm
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°
