Answer:
pretty sure is it B. -1.75 and 4 but not 100% positive
Answer:
Step-by-step explanation:
1) 97 + x = 64 + 27 {Exterior angle property}
97 + x = 91
x = 91 - 97
x = -6
2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}
4x + x + 17 +80 + 23 = 180
5x + 140 = 180
5x = 180 - 140
5x = 40
x = 40/5
x = 8
Answer:
Step-by-step explanation:
So for this, we will be using proportions. In this case, our proportion will be 
Firstly, cross-multiply: 36 = 3x
Next, divide both sides by 3 and your answer will be: 12 = x
