This is the concept of geometry, for us to get the value of JM we will requires to get the value of x first; From the diagram we have been told that; KL=ML KL=7x+7 ML=8x-3 thus; 8x-3=7x+7 collecting the like terms we get; 8x-7x=7+3 x=10 But, JM=13x+2 substituting the value of x in JM we get: JM=13(10)+2 JM=130+2 JM=132 The answer is 132°
