Answer 1

Answer:

x = 11

Step-by-step explanation:

interior angles of a triangle = 180

equation:

⇒ 82 + 31 + 6x + 1 = 180

combine like terms:

⇒ 82 + 31 + 6x + 1 = 180

⇒ 114 + 6x = 180

subtract 114 on both sides:

⇒ 114 - 114 + 6x = 180 - 114

⇒ 6x = 66

divide 6 on both sides:

⇒ 6x = 66

⇒ $\frac{6x}{6} = \frac{66}{6}$

⇒ x = 11
