Two angles that have the sum of 180 degrees are supplementary angles. If you need to find angle A, you just need to subtract angle B from 180 degree to find out the degree of the particular angle. Hope I helped.
Answer:
Okay so for the first box i should be x<-5 and the other box should be -5<x
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.
Add like terms to get 5x - 20 = 180
5x = 200
x = 40
(1,0) and (7,0) are the x intercepts
