Question

37° 108° (x + 5)° o x = 34 o x = 32 o x = 30 o x = 28

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of interior angles of a triangle is 180°. So, \((x + 5)+37+108=180\).

Step2: Simplify the left - hand side of the equation

\((x + 5)+37+108=x+(5 + 37+108)=x + 150\). So, \(x+150 = 180\).

Step3: Solve for x

Subtract 150 from both sides of the equation: \(x=180 - 150\).

Answer:

\(x = 30\)
