Each triangle has a sum of angles that equal 180° so set each angle measure = 180
(x + 66) + (x + 86) + 50 = 180; add accordingly
2x + 202 = 180; subtract 202 from both sides
2x = -22; divide both sides by 2
x = -11
Plug in -11 for x to check
(-11 + 66) + (-11 + 86) + 50 = 180
55 + 75 + 50 = 180
180 = 180 so -11 is the correct value of x
Answer: -1
Step-by-step explanation:
In order to find the slope, you should remember the formula (Y1-Y2)/(X1-X2) the order of the x and ys do not really matter, but the they should be the same for the top and bottom. In this situation, you can do (4-6) which represent your Y1 and Y2 and then divide by (1 minus -1) which are your xs, this simplifies to -2/2 or simply, a slope of -1
