Question

FIND THE MEASURE OF UNKNOWN ANGLES

Answer 1

Answer:

IT IS SIMPLE, LET ME SHOW ME-

Step-by-step explanation:

a) using angle sum property

x+2x+120=180

3x+120=180  

3x=180-120

3x=60

x=60/3

x=20

b=20x2

b=40

120,b=40,c=20

b)linear pair of 115 is 65

so angle sum property=65+65+x=180

130+x=180

x=180-130

x=50
