Question

the measures of the angles of a triangle are shown in the figure below. solve for x. answer attempt 1 out of 10 x =

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°. So, we have the equation \(43 + 72+x=180\).

Step2: Simplify the left - hand side

First, add 43 and 72: \(43 + 72=115\). The equation becomes \(115 + x=180\).

Step3: Solve for x

Subtract 115 from both sides of the equation: \(x=180 - 115\).
\(x = 65\)

Answer:

65
