Question

∠TUV and ∠VUW are adjacent complementary angles. If m∠TUV = 80°, what is m∠VUW?

Answer 1

Since they are adjacent complementary angles, that means angle TUV and angle VUW add to equal 90°. Since angle TUV is 80°, you subtract 80 from 90, which gives you 10°. So, this means angle VUW is 10°.
