Which of the following statements are true? Select all that apply.
(Y=136)

B. x + y = 180° and C. y = z

x = 180° - 82° - 54°

x = 64°

x + y = 180°

64° + 136° = 180°

so, x + y = 180° it's should be correct

∠y°,∠z° are vertical opposite angles.

could you reply to this with the question so i can ?

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
