Answer:
1) x = 80
2) x = 95
3) x = -7
4) x= 32
5) No
Explanation:
1) 180 - 60 - 40 = 80
2) 180 - 35 - 50 = 95
*Those two questions you use 180 (the total degrees of a triangle) to figure out the missing angle.*
3) 180 - 76 - 41 = 63
x + 70 = 63 (subtract 70 to get -7)
*You are trying to find x not the angle. So you need to find the angle (the first part) and plug in to find what x needs to be*
4) 180 - 122 = 58
*Those two angles are supplementary*
180 - 90 - 58 = 32
5) No because the three angles don’t add up to 180
85 + 45 + 45 = 175 Needs to be 180
