Question

In the given figures,find the values of x and y.​

Answer 1

Answer:

x=60°, y=50°

Step-by-step explanation:

130°+y=180°

y=1180°-130°= 50° ----------> 1

x+y+70°=180°

by substituting in 1 we get

x=180°-70°-50°

x=60°

Hope it helps you

Answer 2

angleBCD =130°

angleACB =y

ACD is a straight line which form angle 180°

so, 130° + y = 180

y = 180 - 130

y = 50°

∆ACB = 180°

angle C = 50°

angle A = 70° given

angle B = x find?

50°+70°+ x = 180°

120°+x = 180°

x = 180° - 120°

x = 60°
