Question

a triangle has interior angle measures of 102°, s, and 35°. what is the value of s? s = °

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 102°+s + 35°=180°.

Step2: Simplify the left - hand side

102 + 35+s=137 + s. So, 137 + s=180.

Step3: Solve for s

Subtract 137 from both sides: s=180 - 137.
s = 43.

Answer:

43
