Question

Find the values of the unknowns x and y from the following

Answer 1

Step-by-step explanation:

a x= 30 y= 100

b x= 70 y=60 sum of internal opposite angle is equal to exterior angle of a triangle

Answer 2

Step-by-step explanation:

a) y = 80° ( vertically opposite angles)

so, 50+80+x= 180° ( sum of triangle)

120+x=180°

x= 180-120= 50°

hence the value of x=50° and y= 80°

b) y+120= 180 ( supplimentry angles)

y= 180-120 ,

y=50°

50+50+x= 180 ( sum of triangle)

100+x=180°

x= 180-100

hence value of x= 80° and y= 50°
