Slope = Change in y / Change in x
= 8 - 2 / 3 - 1
= 6 / 2
= 3
Answer:
The answer is 39 square inches.
Each side of the triangle has a little line through them. This means all 3 sides are equal, so all three inside angles would also be equal.
The three inside angles of a triangle need to equal 180 degrees.
Divide 180 by 3 to find the inside angle for each angle:
180 / 3 =60.
Each inside angle needs to be 60 degrees.
Set the equation with x in it to 60 and solve for x:
2x-4 = 60
Add 4 to each side:
2x = 64
Divide both sides by 2:
x = 64/2
x = 32
