Question

I need to find the value of x. Help please

Answer 1

X=68 is the correct answer to your question

Answer 2

Answer:

$x=68$

Step-by-step explanation:

In the figure, we shown all four exterior angles of the polygon. The sum of the exterior angles of any polygon is equal to $360^{\circ}$.

Therefore, we have:

$79+(x+10)+(x-1)+(2x)=360,\\79+x+10+x-1+2x=360,\\88+4x=360,\\4x=272,\\x=\boxed{68}$
