how can you use the sine and cosine ratios and their inverses in calculations involving right triangles
Marysya12 [62]

Answer:

Step-by-step explanation:

I will show you by example.  For the sin ratio, we have that the sin of the reference angle is equal to the side opposite the angle over the hypotenuse of the right triangle.  We use this example for finding the ratio, knowing the angle:

sin(60)=.866025 found on your calculator.  Because this is a special angle in a right triangle, we can also say, by looking at a 60 degree reference angle that the side across from the angle measures square root of 3, and the hypotenuse measures 2.  So in terms of a radical,

sin(60)=\frac{\sqrt{3} }{2}

If we don't know the angle, we use the 2nd button on our calculator to find it.  For example, if our problem looked like this:

sin\theta=\frac{1}{2},

we are asked what angle has a sin ratio of 1/2.  We find this angle by pressing the 2nd button on our calculator, then the sin button and you will see this on your screen:

sin^{-1}(

Enter either a .5 or a 1/2 after that open parenthesis and hit enter and you'll get the angle measure.  That's how you use the inverses to solve for missing angles.

Find x and y <br><br> pls help
ahrayia [7]

Answer:

x = 14

Step-by-step explanation:

110 + 5x = 180

-110 -110

5x = 70

divide by 5 on both sides

x = 14

to find y add 70 + 40 + missing angle = 2y

missing angle is 70 because 70+40+70 = 180

so 2y = 110

y = 55

Suppose the cost of college tuition is expected to increase 5% every year. How much will the tuition at a comunity college cost
evablogger [386]

Answer:

$7,596.43

Step-by-step explanation:

The cost of the college tuition is increasing 5% compounded annually for 5 years.

∴ A = P(1 + r%)ⁿ

where A = tuition fee after 5 years.

           P = current tuition

           r = rate of increase

            n = period

A =  $5,952(1 + 5%)⁵

     = $5,952(1 + 0.05)⁵

     =  $5,952 × 1.05⁵

     = $7,596.43

    =
