Answer:

a) sine
b) 9.8 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA helps you remember the definitions of the trig functions. In particular, the function that involves the Opposite side and the Hypotenuse is the Sine function:

... Sin = Opposite/Hypotenuse

In this problem that means ...

... sin(55°) = x/(12 ft)

Multiplying by 12 ft, we have ...

... (12 ft)·sin(55°) = x ≈ 9.82982 ft ≈ 9.8 ft

Tina had $47.10 in her bank account on Monday. She withdrew $25 on Monday and also made a deposit of an amount d that she cannot

nalin [4]

The correct answer is a. 47.10 - 25 + d = 97.43.

This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.

Also, Tina made a deposit of an amount that she can't remember. A deposit is adding a certain amount of money, so you have to +d.

This rules out option B.

The only option left is option A, which makes complete sense.
