If the measure of an angle is twenty less than the measure of its complement, what is the measure of the angle?

That angle would be 35 degrees. 

Complementary angles equal 90 degrees. So you can create an equation with x as the angle and its complement being x + 20. Set that equal to 90 and solve. 

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
