Question

Solve for x and then find the length of the base of the triangle.

2x-1
X-4
The base of the triangle is
units long.

Answer 1

x=8 and the base is 4 units long.

Explanation:

We know the 2 sides are = so

2x-1 = x+7

Subtract x from both sides

x-1=7

Add 2 to both sides

x=8

We now know that x=8. The base is labeled x-4.

8-4=4 so the base is 4 units long.
