Question

find the value of x , y and z in each of the following figures if l and m and a and b plz anyone say me the answer step by step ​

Answer 1

a) (17x + 4°) = (12° + 15x)

(because both are corresponding angles)

17x - 15x = 12° - 4°

x = 8°/2 = 4°

b) if a is the transversal of l || m.

x = 100°

(because both are corresponding angles)
