Question

What is measure of angle B + Measure of angle C

Answer 1

D

Explanation:

Supplementary angles sum to 180°, thus

∠ A + ∠ B = 180°, that is

30° + ∠ B = 180° ( subtract 30° from both sides )

∠ B = 150°

Complementary angles sum to 90°, thus

∠ A + ∠ C = 90°, that is

30° + ∠ C = 90° ( subtract 30° from both sides )

∠ C = 60°

Thus

∠ B + ∠ C = 150° + 60° = 210° → D

Answer 2

I not to sure but I think it will be A not to sure sorry if wrong ❤️
