Answer 1

Answer:

Angle y= 50°+60°= 110° [exterior angle property]

angle x+ angle y= 180° [ adjacent angles]

angle x= 180°- 110°

angle x= 70°

Answer 2

Answer:

x=70 y=110

Step-by-step explanation:

we know that sum of all angles of a ∆ 180

A+B+C=180

50+60+x=180

110+x=180

x=180-110

x=70

y is an exterior angle so,

A+B= y

50+60=y

110=y
