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

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

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

b) 70

Step-by-step 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)

#CMIIW ^^

y = 40

Step-by-step explanation:

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

the perimeter is increased by a factor of 2

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
