Use the Law of Sines to find mZY.

Mathematics
1 answer:
Scrat [10]3 years ago
3 0

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?

Tell me how you got the answer
Anvisha [2.4K]

Answer:

x = 18; y = 20

Step-by-step explanation:

6.

Triangles KLM and KNO are similar, so the ratios of the lengths of corresponding sides are equal.

KL/KN = LM/NO

10/30 = 6/x

Cross multiply.

10x = 6 * 30

10x = 180

x = 18

KL + LN = KN

10 + y = 30

y = 20

When you raise a number to a negative exponent, change the exponent to a positive and make the complete number a fraction with 1 as the numerator.

5 ^-2 = 1/5^2

The answer is C.
