Answer:
30°
Step-by-step explanation:
RUT= RST ----since they both stand on common arc TR
Thus, RST = 30°
A) Garage A = 3x
Garage B = 2x + 2
b) 2x + 2 = 3x
x = 2
c) the solution, 2, means the number of hour which both garages would have the equal amount of cost. In this case, in 2 hours, they would be equal in cost.
By determining the length of TV using TV^2=15^2+10^2-2(15)(10)cos80, and then determining the value of x using 15^2=TV^2+10^2-2(TV)(10)cosx.
B because if you simplify 9/15 by 3 you have 3/5
