Find the exact values of sin a and cos a. write fractions in lowest terms. (5 points) a right triangle abc is shown. leg ac has length 33, leg bc has length 44, and hypotenuse ab has length 55.

sin a = four fifths ; cos a = three fifths
sin a = three fifths ; cos a = four fifths
sin a = five fourths ; cos a = five thirds
sin a = four thirds ; cos a = three fourths

Solution:

Given a right triangle ABC

The figure is attached below

From given,

AC = Base = 33

BC = Perpendicular = 44

AB = hyptotenuse = 55

We know that,

Also,

Thus the values are found

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
