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

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°.

Step2: Set up the equation

Let the three angles of the triangle be (p), 98°, and 39°. So, (p + 98^{\circ}+39^{\circ}=180^{\circ}).

Step3: Solve for (p)

(p=180^{\circ}-(98^{\circ} + 39^{\circ})) (p=180^{\circ}-137^{\circ}) (p = 43^{\circ})

Answer:

43
