If 2J measures 45'
M measures 40', and jis 7 feet, then find m using the Law of Sines. Round your answer to the nearest tenth.
6.4 ft
7.7ft
8.5 ft
23.7 ft

the answer is B.

Step-by-step explanation:

because it is rounded to the nearest  tenth of the answer

6.4ft

Step-by-step explanation:

i got it right on the test.

<J = 45°

<M = 40°

j = 7 ft

By law of sines:

j/sin(J) = m/sin(M)

7/sin(45) = m/sin(40)

m = 6.4 ft

y=mx+b is the final answer!   : )
