Answer:
cos(x) = 0.6
Step-by-step explanation:
First, we need to find UQ.
UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)
UQ = 24 cm
Then TQ is ...
TQ = 1/3UQ = 1/3(24 cm) = 8 cm
And cos(x°) is ...
cos(x°) = √(1 -sin²(x)) = √(1 -64/100)
cos(x°) = 6/10 = 3/5
cos(x°) = 3/5 = 0.6
The answer for that word problem is A:41balls
Answer:
16.6°
Step-by-step explanation:
area = ab sinθ a and b: base and oblique side length θ: angle between
26 = 9.3 x 9.8 sinθ
sinθ = 26 / (9.3 x 9.8) = 0.285276
θ = 16.6
