Question 156954
The supplement of an angle is 15 less than 4 times the angle. Find the angle.
:
Let x = the angle
then
(180-x) = the supplement of the angle
;
Write what it says:
180 - x = 4x - 15
:
180 + 15 = 4x + x
:
195 = 5x
x = {{{195/5}}}
x = 39 degrees
:
:
Check the solution in the given statement:
180 - 39 = 4(39) - 15
141 = 156 - 15
