So the given angles are supplementary (add to 180). You take the two and add them. 21x+5+37x+1. This gets set to equal 180. 58x+6=180. Subtract 6 from both then divide by 58. You get x=3
54•2=108
36•1=36
108+36=144
14•6=84
144-88=$56
Answer is $56.00
It would quadruple the area of the circle.
0.13 cubic feet. You take all of the three numbers (0.19m,0.28m, and 0.070m) and multiply them.
