Question

Solve for x. pls help !!!!!

Answer 1

Answer:

x=5

Step-by-step explanation:

Put everything on one side of the equation and have it equal to 180 degrees.

13x+3+72+8x= 180

Combine like terms

21x+75= 180

Subtract 75 on both sides

21x = 105

Divide by 21 on both sides

x= 5

hope this helped!
