Question 510260: if four times the supplement of an angle is added to either times the angles complement, the sum is equivalent to three straight angles. find the measure of the angle that is supplementary to the complement.
4(180-x)+8(90-x)=3(180)
That should be the equation but I've tried to solve it and can't!!
Help! Please and Thank you!!

Question 510290: The measure of an exterior angle of a regular polygon is given. Find the measure of an interior angle, and find the number of sides. The measure of the exterior angle is 72 degrees.
I found that the adjacent angle is 108 degrees. That is as far as I got. Can you explain this? Thank you.

Question 511829: The measure of the supplement of an angle is 40 more than 2 times the measure of the compliment of the angle. Find the measure of the angle
Here is what i have tried so far
90-x = compliment of angle
180-x =suppliment of angle
180-x= 2(90-x)+40
180-x=180-2x+40
180-x=220-2x
180+2x=110
2x=55
I think my set up is wrong could u please show me the correct set up and answer
thank you
