Answer 2

Answer:

75 degree is your ans

constitution draw a horizontal a and b which touch point k

now we have to triangle

in upward the 180-140= 40 now we draw a line which is horizontal see that it is straight the it is 90 dgree

90+40= 130. now triangle some is 180 - 130= 50 we get at k near is 50

now in down side same

now we add both near of k 50+55+105

so we see that point k is 180 degree parallel line which we draw so 180-105=75
