Question

Use the Law of Sines to find mZY.

Round to the nearest degree.
X
14 m
30 m
123°
Z

Answer 1

Explanation:

recall law of Sines :) the same as before Sin(A) /a = Sin(B) / b

[ when you see it a lot.. you'll remember it :D ]

for this problem Z =A=123 and a = 30

Y=B and b =14

Sin(123) / 30 = Sin(B) / 14

14 * 0.0279556 = Sin(B)

0.391379 = Sin(B)

arcSin(0.391379 ) = arcSin ( Sin (B) )

23.040 = B

Y = 23.0°

are you seeing how to do these? so you could on a test?
