The measure of zabc is 130º. find
the value of x.

(6x+40)°

x = 15

Step-by-step explanation:

If ZABC = 130º

ZABC = (6x+40)° = 130º

This equation can be rearranged to solve for x by isolating it (moving everything over to the other side).

(6x+40)° = 130º

Solve it without the degrees sign because it looks confusing.

6x+40 = 130

6x+40 - 40 = 130 - 40   (subtract 40 from both sides)

6x = 90

6x/6 = 90/6    (divide both sides by 6)

x = 15

Therefore x is 15. The degrees symbol is already included outside the bracket.
