Question

solve for x.* your answer

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, we set up the equation $(7x + 9)+65 + 36=180$.

Step2: Combine like - terms

First, add the constant terms on the left - hand side: $7x+(9 + 65+36)=180$, which simplifies to $7x + 110=180$.

Step3: Isolate the variable term

Subtract 110 from both sides of the equation: $7x=180 - 110$, so $7x = 70$.

Step4: Solve for x

Divide both sides by 7: $x=\frac{70}{7}=10$.

Answer:

$x = 10$
