The composition of 2 functions is B
I think the answer is 80 degrees. Think about it like you're moving the chunk with 100 degrees already filled in, to the space where you're trying to find the amount since they're the same. Vertical angles are supplementary and are equal to 180. So, 100+x = 180. x would equal 80 degrees.
Yes, SSS
PR are already a given side. PS and PQ are also given sides. Lastly, RS and RQ are given sides.
Another unit would be how many METERS have that person ran
The final solution is y=-5/3x-10
