Question

solve for x. 8x + 2 70° 60° your answer

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, $(8x + 2)+70 + 60=180$.

Step2: Simplify the left - hand side

Combine like terms: $8x+(2 + 70+60)=8x + 132$. So, $8x+132 = 180$.

Step3: Isolate the variable term

Subtract 132 from both sides: $8x=180 - 132$.
$8x=48$.

Step4: Solve for x

Divide both sides by 8: $x=\frac{48}{8}$.
$x = 6$.

Answer:

$x = 6$
