Answer :
Final answer:
In triangle JKL, the measure of angle KLM is the same as the measure of angle L in triangle JML.
Explanation:
In a right triangle, the angle opposite the hypotenuse is called the right angle. So in triangle JKL, angle K is the right angle. Since triangle JML is an isosceles triangle with JL congruent to ML, angles J and L are congruent to angles JKL and JKM (respectively) since they are opposite congruent sides. Therefore, in triangle JML, angle L is congruent to angle KLM. So the measure of angle KLM is the same as the measure of angle L in triangle JML.

Okay so we know angle JLK= 42+90-180 which equals 48. We know this because the angles of a triangle added together equal 180. We also know angle LMJ=63 since it’s an isosceles triangle so that mean angle MLJ equals (63+63-180=) 54 and to find the measure of angle KLM we add the measure of JLK and MLJ which gives us 48+54=102. So 102 is the answer. Hope this helps
