Question

find x and y in each of the following ​

Answer 1

Step-by-step explanation:

i) y+100=180. (linear pair)

y=80

in triangle ABC

y+60+x=180. (angle sum property)

80+60+x=180

x=40

ii)2x+3x+x=180. (angle sum property)

5x=180

x=36

now y+x=180. (linear pair)

y+36=180

y=144

iii) y+120=180. (linear pair)

y=60

y+x=100. ( exterior angle is equal to sum of interior opp angles)

60+x=100

x=40

hope it helps
