m < A = 138...and since < A and < B make a straight line...and a straight line measures 180, then < B = (180 - 138) = 42.
A triangle has interior angles that add up to 180. So < B + < H + < C = 180.
and we know < B = 42 and < H = 56.....42 + 56 + < C = 180.
98 + < C = 180....< C = 180 - 98.....< C = 82
also, < D + < C = 90 because they form a right angle.....so < D + 82 = 90....
< D = 90 - 82...< D = 8.
< G and < H form a straight line...so they add up to 180....and < H is 56, so < G = 180 - 56 = 124
and remember that angles in a triangle add up to 180.
< D + < G + < E = 180.....8 + 124 + < E = 180
< E = 180 - 132 = 48
to help with the rest of them..
< H + < K = 180
< G + < J = 180
< E + < F = 180
