How many triangles can be made with a 70 degree angle a 30 degree angle and an 80 degree angle

There are infinite number of triangles that could be achieved with those angles.

To picture this, we only have to imagine a triangle that is either smaller or bigger than the one at hand.

Tracing a series of paralell lines (which guarantee that the angles are being kept),  we can draw triangles for infinite values of x,y and z.

b.an increase in a causes b to decrease

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
