Answer 1

can someone help me please

Answer 2

Do you know the law of Cosine of law of sines yet?

Answer 3

ok... to solve this question there are several steps

find the angle N using the sine rule...

when you have that, find the angle K using angle sum of a triangle.

Lastly to find NM you need to use the cosine rule..

the cosine rule needs the included angle..... or the angle between the 2 sides with measurements. Thats why you can't use the cosine rule from the start

Answer 4

sine rule and cosine rule are the same as law of sines and law of cosines
