The following triangle is isosceles. Write an equation and use it to solve for x. Options:

x = 3
x = 2
x = 6
x = 4

x = 6

Step-by-step explanation:

Since the sides are congruent (definition of isosceles triangle), the angles must also be congruent.

Step 1: Set up equation

4x + 20 = 8x - 4

Step 2: Solve for x

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
