Answer:

x = 15

Step-by-step explanation:

Since this is an isosceles triangle, the angles at the bases of the like sides must be the same measure

3x = 5x-30

Subtract 5x from each side

3x-5x = 5x-5x-30

-2x = -30

Divide each side by -2

-2x/-2 = -30/-2

x = 15

Answer:

B.) X = 15

Step-by-step explanation:

3x = 5x - 30

3x - 5x = 5x - 5x - 30

-2x = -30

-2x/-2 = -30/-2

X = 15
