Sinx=11/12
x=arcsin(11/12)°
x≈66° (to nearest whole degree)
...
sinα=(side length opposite angle α)/(length of hypotenuse)
Answer:
B. cost(time)
Step-by-step explanation:
In the information given above, you can eliminate choices "A," and "D," since they're just using the cost of a repair and the time the mechanic works. This leaves us with either "B," or "C." The correct answer is "B," because the cost of the repair depends on whatever is inside the parenthesis (the time).
Equilateral triangles have three equal angles, so we right away know that x=60º. Then, we just solve (3(60)-70)º, which is 110º, for the answer.
