Question

Use the Law of Sines to find mZY.

Answer 1

Answer:

Step-by-step 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?
