To solve for x, we know that the sum of the interior angles of a triangle is always 180°.
So, we can set up the equation:
(8x+6) + 60 + x = 180
Combine like terms:
9x + 66 = 180
Subtract 66 from both sides:
9x = 114
Divide by 9:
x = 12
Therefore, x = 12.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(8x+6)°
60°
