State if the two triangles are congruent. if they are, state how you know.

Yes, both triangles are congruent to each other by SIDE ANGLE SIDE property of congruence.

Step-by-step explanation:

Two triangles are said to be congruent if and only if they have same corresponding angles and sides.  

Now, here

Side 1 = Side 2 (given)

Side 3 = Side 4  (given)

Central angle of triangle 1 = Central angle of triangle 2 (Vertically Opposite)

Hence, by the rule of SIDE ANGLE SIDE (SAS) rule of congruence ,

Triangle 1 ≅ Triangle 2

part a

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
