question\nfind the measure of the missing angle.\nanswer attempt 1 out of 2\na =

Answer

Explanation:

Step1: Recall angle - sum property

The sum of angles on a straight - line is 180°. Also, we have a right - angle (90°) and a 38° angle. Let the missing angle be (a). Then (38^{\circ}+90^{\circ}+a = 180^{\circ}).

Step2: Solve for (a)

First, simplify the left - hand side: (38 + 90=128). So, the equation becomes (128^{\circ}+a = 180^{\circ}). Subtract 128° from both sides: (a=180^{\circ}-128^{\circ}). (a = 52^{\circ})

Answer:

(52^{\circ})
