Question

the measures of the angles of a triangle are shown in the figure below. solve for x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\). So, \(x + 43 + 80 = 180\).

Step2: Solve for x

Simplify the left side: \(x + 123 = 180\). Subtract 123 from both sides: \(x = 180 - 123\). \(x = 57\).

Answer:

\(x = 57\)
