Answer:
is the correct answer.
Step-by-step explanation:
![\tan \left(30^{\circ \:}\right)=\frac{x}{150}\quad :\quad x=50\sqrt{3}\quad \left(\mathrm{Decimal}:\quad x=86.6\dots \right)\\\\\sin \left(60^{\circ \:}\right)=\frac{y}{86.6}\quad \rightarrow\quad y\approx75](https://tex.z-dn.net/?f=%5Ctan%20%5Cleft%2830%5E%7B%5Ccirc%20%5C%3A%7D%5Cright%29%3D%5Cfrac%7Bx%7D%7B150%7D%5Cquad%20%3A%5Cquad%20x%3D50%5Csqrt%7B3%7D%5Cquad%20%5Cleft%28%5Cmathrm%7BDecimal%7D%3A%5Cquad%20x%3D86.6%5Cdots%20%5Cright%29%5C%5C%5C%5C%5Csin%20%5Cleft%2860%5E%7B%5Ccirc%20%5C%3A%7D%5Cright%29%3D%5Cfrac%7By%7D%7B86.6%7D%5Cquad%20%5Crightarrow%5Cquad%20y%5Capprox75)
I don't want to give you the answer so here is a thorough explanation and an answer if you want it. Set this up as a proportion. Set it up as 5/5=x/12.5. Then multiply 5 by x to get 5x and 12.5 by 5. Once you have this answer, divide it by five to isolate the x. Once you have finished this, you have your answer.
I got the answer 12.5. Make sure you check this so you understand how to solve these kinds of problems.
-61 + (-143) = -204
Add them both, I suppose.
