![\boxed{ \bold{ \huge{ \tt{x = 6°}}}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/hx0keznb26y20c2yyaptarq8ta74y65ox4.png)
Explanation:
The angles which are formed inside by the joining of arms of triangle is called interior angles . Remember that the sum of interior angles of a triangle is always 180° . Let's create an equation and solve for x.
![\text{8x + 2 + 70 + 60 = 180}](https://img.qammunity.org/2021/formulas/mathematics/high-school/sy1oix4kqd0f43wi2r5b1m2wk1xy3901m5.png)
{ Add the numbers : 2 , 70 and 60 }
{ Move 132 to right hand side and change it's sign }
{ Subtract 132 from 180 }
{ Divide both sides by 8 }
![\boxed { \text{➸ x = 6°}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/4b8tlu6pprptj42d2p1vab62z2he4mcz81.png)
