triangle JKM with side j across from angle J, side k across from angle K, and side m across from angle M If ∠J measures 45°, ∠M measures 40°, and j is 7 feet, then find m using the Law of Sines. Round your answer to the nearest tenth.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

9x

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
