If the m∠A is 29°, what are the m∠B and m∠C?)

A. m∠B= 119°, m∠C = 151°
B. m∠B= 61°, m∠C = 151°
C. m∠B= 119°, m∠C = 61°
D. m∠B= 61°, m∠C = 119°

Step-by-step explanation:

m∠A = 29°

∠A and ∠B are complementary, then

m∠A + m∠B = 90°

29° + m∠B = 90°

m∠B = 90° - 29°

= 61°

∠B and ∠C are supplementary, then

m∠B + m∠C = 180°

61° + m∠C = 180°

m∠C = 180° - 61

= 119°

therefore the answer is D. m∠B = 61°, m∠C = 119°
