Question

How do I solve for x? Would my answer be 27?

Answer 1

Given

To find the value of x.

Now,

By the external angle sum property of triangle, we have,

`(4x+2)\degree+(2x-9)\degree=5x+13\degree`

That implies,

`\begin{gathered} 4x+2+2x-9=5x+13 \\ 6x-7=5x+13 \\ 6x-5x=13+7 \\ x=20\degree \end{gathered}`

Hence, the value of x is 20 degrees.
