Question 1201387
<pre>
the complement of an angle is 20 degrees less than 4 times the angle. find the angle

Let angle's measure be A
Then its complement is: 90 - A
   We then get: 90 - A = 4A - 20
              - A - 4A = - 20 - 90
                  - 5A = - 110
Angle's measure, or {{{highlight_green(matrix(1,5, A, "=", (- 110)/(- 5), "=", highlight(22^o)))}}}</pre>
