Answer:
36
Step-by-step explanation:
Kendra has 4 so 52-4 (so it's out of the way) now you have 48
Divide 48 by 3 (leaves you 16). It can't be 16 because you have to add 16 and the sum of 16 x 3. So, go down a few numbers
12 + (12x3) = 48 plus Kendra's 4 is 52
These two triangles are congruent via the Side Angle Side Axiom, therefore JM is = KM. Then 9x-18 = 3x and solving for x gives us 6x = 18 or, x = 3
