the diagram shows a triangle. what is the value of u? u = °

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 70° + 47°+(u - 44°)=180°.

Step2: Simplify the left - hand side

First, combine the constant terms: 70°+47° - 44°+u=180°. 70 + 47-44=73, so 73°+u=180°.

Step3: Solve for u

Subtract 73° from both sides of the equation: u=180° - 73°. u = 107°.

Answer:

107
