Line et is a tangent to circle a at point t and the measure of ∠tng is 25° what is the measure of ∠net? a) 130° b) 50° c) 65° d) 90°

C) 65°

Step-by-step explanation:

G ∈ NE, so ∠TNG = ∠TNE. ∠ATE = 90° because a radius (AT) is always perpendicular to a tangent line (ET) at the tangent point (T). A ∈ TN, so ΔTNG is a right triangle, and angles NET and TNE are complementary. Then ...

... ∠NET = 90° - ∠TNG

... = 90° - 25°

... ∠NET = 65°
