Question 159957: hi, im working on complements and suplements of angles and i had a question from my worksheet.
"The measure of the complement of an angle is 45+x. The measure of the supplement of an angle is 15x-47. What is the measure of the angle?"
My work: 45 + x = 90 15x - 47 = 180 15x 227
-45 = -45 +47 = +47 ---- = --- =(x = 15.13333333)
------------- --------------- 15x 15x
(x = 45) 15x = 227
what i dont get is what to do next. the question is asking for only one of the angles but i have two x's. If i plugg them in then i have two different answers. What should i do next to finish this problem?

Question 161400: Building a hexagon shaped patio with six equal sides.The ciritical measurement is from the vertex of one angle across the hexagon to the opposite vertex.The measurement is 15 feet. What will be the area of the patio in sqaure feet?
I figured out there will be 6 triangles and I have to use the pythorean theory to find the measurements of all six triangles. One measurement must be 7.5 ft. beacause that is half of 15 ft. After I find the height of the triangles I know I would use the A=1/2 bh formula to find area. I am not sure how to put it all together.
