Write an equation for the sum of the angles in this triangle. Use your equation to find the value of $x$.
Give your answer in degrees $\left(^{\circ}\right)$.
Not drawn accurately
\(x = \boxed{22.5^\circ}\)
Step 1 :\(x + 2x + 5x = 180^\circ\)
Step 2 :\(8x = 180^\circ\)
Step 3 :\(x = \frac{180^\circ}{8}\)
Step 4 :\(x = \boxed{22.5^\circ}\)
