Slope is always (y2-y1)/(x2-x1) in this case:
(-2-3)/(6--4)
-5/10
-1/2
Answer:
9 sides
Step-by-step explanation:
7y + 2y = 180
9y = 180
y =20
so, 2y, the exterior angle is 2 x 20 = 40
Divide 360 by 40 = 9
Answer:
x = 25
Step-by-step explanation:
Given:
- ∠A = ∠B (Vertically opposite angles)
- ∠A = (7x - 8)°
- ∠B = (6x + 17)°
Since ∠A is equivalent to ∠B...

Open the parenthesis:

Add 8 both sides:

Simplify both sides:

Subtract 6x both sides:

Simplify both sides:

34/85%=34/0.85=40
So that's your answer.
