Question

1 solve for x by using the triangle sum theorem: 36° x° 51° g h x = degrees

Explanation:

Step1: Recall triangle - sum theorem

The sum of interior angles of a triangle is 180°. So, $36^{\circ}+x^{\circ}+51^{\circ}=180^{\circ}$.

Step2: Simplify the left - hand side

$36 + 51+x=180$, which gives $87 + x=180$.

Step3: Solve for x

Subtract 87 from both sides: $x=180 - 87$.
