what is the value for y?

y =14

Step-by-step explanation:

we know that <a = <b since it is an isosceles triangle

<a = <b = 50

the triangle add to 180 degrees

<a + <b + <c =180

50 + 50 + <c = 180

add like terms

100 + <c = 180

subtract 100 from each side

<c = 180-100

<c = 80

<c = 5y+ 10

80 = 5y+10

subtract 10 from each side

80 -10 = 5y+10-10

80-10 = 5y

70 = 5y

divide by 5

70/5 =5y/5

14 = y

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
