Question

a triangle has interior angle measures of 38°, 88°, and c. what is the value of c? c = °

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 38° + 88°+c = 180°.

Step2: Simplify the left - hand side

38 + 88=126, so the equation becomes 126°+c = 180°.

Step3: Solve for c

c = 180° - 126°.
c = 54°.

Answer:

54
