Answer:

A) x=42\sin32^\circ

Step-by-step explanation:

With respect to our angle, the side opposite to it is x, and the hypotenuse is 42, so the trig ratio we need to use here is sine as \displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}. Hence, if we rearrange the equation so that we solve for the opposite side x, then we'll have (\text{hypotenuse})(\sin\theta)=\text{opposite}\rightarrow42\sin32^\circ=x as the correct equation.

A kitten was given to a child as a birthday present when she was two years old. The cat lived a good life, but eventually became
Katyanochek1 [597]

Answer: 14 years

Step-by-step explanation:

Let the cat's age when it died = x.

Therefore, the child's age is 2 + x because he/she got the cat when he/she was 2 years old.

We can set up an equation.

x + (2+x) = 30

2x + 2 = 30

2x = 28

Therefore, x = 14
