If I have an angle whose measure is 10 degrees more than twice it's complement, what is the measure of that angle?

the complement is the angle that adds to the number to equal 180 so the solution is to subtract ten the divide by two and you have your answer of 85.

Two angles are complementary if they add to 90 degrees.

So, if we call our angle A, its complement will be 90 - A.

Twice its complement will be 2 (90 - A).

Our angle is 10 degrees more than that, so,

A = 10 + 2 (90 - A).

Now do the algebra to calculate A.

For starters, complementary angles add up to 90 degrees.

It is supplementary angles that add to 180 degrees.

This may help you remember. 2*90=180 and 2 Cs make an S. I am talking visually. An S has a C at the top and a back-to-front C on the bottom

I see Bertie has just answered so I don't need to say more. Thanks Bertie.
