Question

please help!!
solve for y (image in the replies)

Answer 1

The three tick marks on each side indicate that all three sides are congruent

So all three angles are congruent

if each angle is Z, then

Z+Z+Z = 180
3Z = 180
Z = 60

So each angle is equal to 60 degrees

Do you agree so far?

Answer 2

yes

Answer 3

so angle C is 60 degrees

angle C = 60
6x+6 = 60

do you see how to solve for x?

Answer 4

i need to solve for y

Answer 5

same idea for angle A

angle A = 60 degrees
5y+10 = 60

do you see how to get y all by itself?

Answer 6

yes

Answer 7

tell me what you get

Answer 8

22?

Answer 9

both of the angles have to equal the same and if you put 4 in for both x and y you get an equal number. so i would say y=4

Answer 10

Let's solve for y

5y+10 = 60

5y+10-10 = 60-10 ... subtract 10 from both sides

5y = 50

5y/5 = 50/5 ... divide both sides by 5

y = 10

let me know if those steps make sense or not
