If j is 21 inches, k is 12 inches, and ∠M measures 62°, then find m using the Law of Cosines. Round your answer to the nearest tenth. a) 883 in b) 348 in c) 29.7 in d) 18.7 in

d. (18.7)

Step-by-step explanation:

The formula for the law of sines in order to find m^2

This equation was derived because:

m=the side you are finding

j=side that is adjacent to M, the angle with side m as its opposite

k=side that is also adjacent to M

In short,

(The opposite side of angle)^2=(Adjacent side of angle)^2 + (The other adjacent side of angle)^2 - (the adjacent side) (the other adjacent side

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
