JM is equal to half of JK so your equation would be set up like this; 4x+1=5x-3 and then you would combine like terms and get 4=x. You would then plug that into the equation for JM; 4(4) + 1= 17.
Hope I didn’t mess up feel free to ask questions :)

Step-by-step explanation:
It is the first one for sure! Hope this helps
By similar triangles:-
2 / x = x / 4
x^2 = 8
x = sqrt 8 = 2.83
y^2 = 4^2 + x^2
= 16 + 8
y = sqrt24 = 4.90
