Answer:
A. 3
Step-by-step explanation:
You can see that the y-values are increasing by 3.
Slope = Rise/Run
So if you rise 3 and run 1, you have 3/1 which is 3.
54/3= 18
18•2=36
36+18=54
The shortest piece is 18in
Answer:
Each angle is 60°
Step-by-step explanation:
The 2 angles are equal to each other because they're alternate exterior angles:
10x - 20 = 7x + 4
10x - 7x = 4 + 20
3x = 24
x = 8
10x - 20
10(8) - 20
80 - 20
60
Since these angles are exterior angles, their angle measures are equal so they both are 60°
