Question

solve for the given variable. 68° 53° b° b = ____

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, 68°+53° + b°=180°.

Step2: Combine like - terms

68 + 53=121, so the equation becomes 121 + b=180.

Step3: Solve for b

Subtract 121 from both sides of the equation: b = 180 - 121.
b = 59

Answer:

59
