Answer :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

diagram

Step 02:

angles:

we must analyze the diagram to find the solution.

a = (180 - 115)° = 65°

b = 115°

c = 65°

d = (180 - 135)° = 45°

f = 110°

g = (180 - 110)° = 70°

h = 110°

j = (180 - 65)° = 115°

k = (180 - 45 - 70)° = 65°

m = (180 - 42)° = 138°

n = (180 - 42 - 65)° = 73°

p = (180 - 73)° = 107°

q = (180 - 107)° = 73°

r = (180 - 68)° = 112°

s = (540 - 135 - 115 - 107 - 115)° = 68°

t = (360 - 124 - 73 - 112)° = 51°

u = 135°

v = 45°

w = (180 - 45 - 65)° = 70°

x = (180 - 65)° = 115°

That is the full solution.
