LIST THE ORDER TO WRITE AND SOLVE THE EQUATION FOR X

Question

A. WRTE THE EQUATION <1 + <2 + <3 = 180 degrees

B. X = 3

C. DIVIDE BOTH SIDES OF THE EQUATION BY 8

D. SUBTRACT 156 FROM BOTH SIDES OF THE EQUATION

COMBINE LIKE TERMS : 45 + 90 + 21

Answer 1

The correct order to write and solve the equation for x is as follows:

1. Write the equation: <1 + <2 + <3 = 180 degrees
2. Combine like terms: 45 + 90 + 21 = 156 degrees
3. Subtract 156 from both sides of the equation: <1 + <2 + <3 - 156 = 180 - 156
4. Simplify: <1 + <2 + <3 - 156 = 24 degrees
5. Divide both sides of the equation by 8: (<1 + <2 + <3 - 156) / 8 = 24 / 8
6. Simplify: (<1 + <2 + <3 - 156) / 8 = 3 degrees
7. Solve for x: X = 3
