Question

Find the value of x and y

Answer 1

Step-by-step explanation:

1) y = 80⁰ ...vertically opposite angels

x= 50⁰... remaining angle of TRIANGLE or sum of measures of all angels of a triangle is 180⁰

2)y= 70⁰... remaining angle of TRIANGLE

x= 110⁰ ... angels in a linear pair

Answer 2

a) 80 degree = y (vertically opposite angle)

y+50+x=180(angle sum property)

80+50+x=180

130+x=180

x=180-130

x=50 degree

b) x=50+60(exterior angle property)

x=110 degree

x+y=180(linear pair)

110+y=180

y=180-110

y=170 degree
