Question

please find the attached

Answer 1

x=23
y=58
hope it helps

Answer 2

angle A is 64degree
angle C =angle A
therefore 64=64
angle x = half of angle C
x= 32 degrees
angle C+ angle B =180 ( linear pair of angles)
let angle B be x
64+x=180
x=180-64
x=116

therefore half of angle B=y
y=116/2
y=58 degrees...
