What is the value of y?

hai

a triangle's sum of interior angels is equal to 180°.

so we have this equailty

y+10°+50+2y = 180

3y+60° = 180.

to solve better, im throwing 60 near 180. 60° is going to be -60 cause of it.

3y=180-60 = 3y=120

now im dividing both 3. because both can divide by 3.

3y/3 = 120/3 = y=40

good luck(:

no not all of them.

step-by-step explanation:

some of them have a square base.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
