Answer:

A. 40 degree+ 90 degree = x

The sum of the angles = 130 degree

Step-by-step explanation:

Given:\:\:\angle RSV = 40\degree,\:\:\angle VST = 90\degree\\\because \angle RSV + \angle VST = \angle RST\\\therefore 40\degree + 90\degree = x

x = 130 degree

From here, we need to start by making an equation:

We know that it has a common difference of 6, thus, the slope is -6.

22 = -6(6) + b
b = 58

So we have our equation:

&#10;y = -6x + 58

Let's plug 50 in and we get -242
