Question

If Y +Y + 40 = 180 in an isosceles triangle so Y =?

a) 140
b) 70
c) 110
d) 0

Answer 1

y = 40

Explanation:

because y = 40 +y =40 +40 =180

Answer 2

If Y +Y + 40 = 180 in an isosceles triangle so Y =?

Answer:

b) 70

Explanation:

Y + Y + 40 = 180

2y + 40 = 180

2y = 180 - 40

2y = 140

y = 140/2

y = 70

So, the value of Y is 70 (b)
