Question

a triangle has interior angle measures of 47°, z, and 97°. what is the value of z? z = °

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, 47°+z + 97°=180°.

Step2: Simplify the left - hand side

47°+97° = 144°, so the equation becomes 144°+z=180°.

Step3: Solve for z

z = 180° - 144°.
z = 36°.

Answer:

36
