Question

a triangle has interior angle measures of 38°, v, and 87°. what is the value of v? v =

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of interior angles of a triangle is 180°. So, 38°+v + 87°=180°.

Step2: Simplify the left - hand side

38°+87°+v=125°+v. So, 125°+v = 180°.

Step3: Solve for v

Subtract 125° from both sides: v=180° - 125°.
v = 55°.

Answer:

55
