Question

What is the measure of NET?

50°
65°
90°
130°

Answer 1

The measure of the angle NET is 65 degrees (choice #2)

Explanation:

Because ET is tangent, <NTE is 90 degrees. Since we are given <TNG=25 degrees, we can use the fact that the sum of the angles in the triangle ENT is 180 degrees to calculate the remaining <NET:

<NET = 180 - 90 - 25 = 65 degrees
