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.

x=8 and the base is 4 units long.

Step-by-step 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.

20335+282=20617
