its 100

OpenStudy (anonymous):

we are looking for angle B or K

OpenStudy (anonymous):

D = M = 86 C = L = 41 A = J = 133

OpenStudy (jdoe0001):

the shapes are similar thus the "corresponding angles" and sides are also similar for angles, they're congruents so angle C = angle L and you're just missing angle K well, they're both quadrilaterials, 4 sides and the sum of a quadrilateral's internal angles is 360 so you have J, M and L subtract them from 360, and that'll be K

OpenStudy (anonymous):

sum of angles in a quadrilateral is 360 so angle B/K is 360 - (133+41+86)
