Question

a triangle has interior angle measures of 32°, 89°, and w. what is the value of w? w = (square^{circ})

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 32°+89° + w=180°.

Step2: Simplify the left - hand side

32 + 89=121, so the equation becomes 121°+w = 180°.

Step3: Solve for w

w=180° - 121°.
w = 59°.

Answer:

59
