Question

a triangle has interior angle measures of 43°, v, and 98°. what is the value of v? v = (square^{circ})

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 43°+v + 98°=180°.

Step2: Simplify the left - hand side

43 + 98+v=141 + v. So, 141 + v=180.

Step3: Solve for v

Subtract 141 from both sides: v=180 - 141.
v = 39.

Answer:

39
