It cannot be factored, so it is prime.
Answer:
angle Z=20°
side xy≈15.36
hypotenuse≈19.49
Step-by-step explanation:
Find angle z adding the other two angles and subtracting that by 180 to get 20.
(12)tan(20) gets you side xy which is 15.36
12^2+15.36^2=xz^2
Answer:.
....
Step-by-step explanation:
Answer:
x = -21
Step-by-step explanation:
62 + 2x - 20 = 0.
Combine like terms
42 +2x =0
Subtract 42 from each side
42-42 +2x = 0-42
2x = -42
Divide each side by 2
2x/2 = -42/2
x = -21
