Question

a triangle has interior angle measures of 43°, 44°, and u. what is the value of u? u =

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, 43°+44° + u=180°.

Step2: Simplify the left - hand side

43 + 44=87, so the equation becomes 87°+u = 180°.

Step3: Solve for u

Subtract 87° from both sides of the equation: u=180° - 87°.
u = 93°.

Answer:

93
