Question

calculate the size of angle x and angle y

Answer 1

amgle x=180-(58=73)=180-131=49.degrees
let the angle next to 90 be angl1
therefore angle 1 =90 degree
therefore angle y+anglex+90=180
angle y=180-(49+90)=180-139=41 degrees.

Answer 2

value of x = 58° + 73°+ x= 180° ( ASP)
131°+ x= 180°
x= 180°-131°
x= 49°

and value of y= 49° + 90°+ y = 180° (ASP)
139°+y= 180°
y= 180°-139°
y= 41°
