Question

solve for x. 70° 65° x + 53

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 $(x + 53)+70 + 65=180$.

Step2: Simplify the left - hand side of the equation

First, add the constant terms: $53+70 + 65=188$. The equation becomes $x+188 = 180$.

Step3: Solve for x

Subtract 188 from both sides of the equation: $x=180 - 188$. So, $x=-8$.

Answer:

$x = - 8$
