For the diagram shown, x = 80 and y = 30. Determine the value of z.
A) 20
B) 40
C) 50
D) 100

C) 50

Step-by-step explanation:

x+90+90+y+z=360

270+y+z=360

y+z=90

Therefore, C) 50

(4,5

look up a corrdinate plane and do what the thingy says and boom

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.
