Answer:
z = 13
Step-by-step explanation:
Opposite sides of a parallelogram are equal. Therefore:
3z = z + 26
Subtracf z from each side
3z - z = 26
2z = 26
z = 26/2
z = 13
Answer:
OC
Step-by-step explanation:
The x value is the same on both side of the equation but the other number are not (8≠-5) so the equation can't be true no matter the value plugged for x
Sinθ = 16/20 = 0.8
θ = arcsin(0.8) ≅ 53°
