Answer:
22.5
Step-by-step explanation:
All of the angles inside the triangle equals 180. Therefore, the equation is x+2x+5x=180. Then, you solve for x. The final equation should look like 8x=180 And that is how we get 22.5
Answer:
22.5
Step-by-step explanation:
The sum of the interior angles in a triangle is 180 degrees, so we have the equation $x+2x+5x=180$, so $x=\boxed{22.5}$.
