Question

Find the unknown angle 56°

Answer 1

The sum of angle 36 degree and 3x is equal to 180 degree. So equation for x is,

`3x+36=180`

Simplify the equation for x.

`\begin{gathered} 3x+36=180 \\ 3x=180-36 \\ x=(144)/(3) \\ =48 \end{gathered}`

So value of x is 48.

The equation is 3x + 36 = 180 and value of x is 48.
