Answer 2

ABC congruent to JKL.....this means that A = J, B = K and C = L

m < B = 55....so < K = 55 also
m < L = 25.....so < C = 25 also
so we need the measure of < J....and < A

interior angles of a triangle add up to 180 degrees
< J + < K + < L = 180
< J + 55 + 25 = 180
< J + 80 = 180
< J = 180 - 80
< J = 100......so < J = 100....and so does < A
