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).
Answer:
58°
Step-by-step explanation:
A + B + C = 180 °
The smallest value of C is 91.
A + B = 89
A = 2B - 4
2B - 4 + B = 89
3B - 4 = 89
3B = 93
B = 31
A + 31 = 89
A = 58

See below.
Step-by-step explanation:
Convert the cotangent to cosine over sine:
Use the cofunction identities. The cofunction identities are:
To convert this, factor out a negative one from the cosine and sine.
Recall that since cosine is an even function, we can remove the negative. Since sine is an odd function, we can move the negative outside:
