Question

The measure of an angle is 40 degrees less than four times the measure of its complement. Find the measure of the angle.

Answer 1

Call x the angle. Complement of x: 4(90 - x)
x = 4(90 - x) - 40 = -4x + 320
x = ...

Answer 2

can you solve it all the way

Answer 3

Answer 4

Actually, if \(x\) is the angle, the complement is \(90-x\), not \(4(90-x)\)

Subsequent lines appear correct, however.

Answer 5

\[x = 4(90-x) -40\]@cutegirl
What do you get if you use the distributive property to remove the parentheses?
