Answer:

you have to use the Pythagorean theorem. a^2 + b^2= c^2

72^2 + b^2 = 75^2

5184 + b^2 = 5625 (subtract 5184 from both sides)

b^2= 441 (find the square root of each side)

b= 21

HELP PLZ!!! LOTS OF POINTS
Darya [45]

I'm going to assume that the ' 7.51 ' is the angle expressed in radians.
So this is just like any other unit conversion exercise.

You know that                  180 degrees = pi radians.

Divide each side by pi radians, and you have

                      180 degrees / pi radians = 1 .

Great !  Now take the angle you have ... 7.51 radians ...
and multiply it by ' 1 '.

      (7.51 radians) x (180 degrees / pi radians) =

<em>                              </em> (7.51 x 180 / pi) degrees =<em>  430.29 degrees</em>


As you ( I ) worked through this problem, a very useful number
fell out . . .  It's  180/pi  =  57.296 ,  or just  <em>57.3</em>  is close enough.

Here's how you can use that number:

-- 1 radian  =  <u>57.3</u>  degrees

-- 1 degree  =  1/57.3  of a radian

-- Got some radians ?  Multiply by  <u>57.3</u>  to get degrees.

-- Got some degrees ?  Divide by  <u>57.3</u>  to get radians.

The relationship between gallons and liters and a currency exchange rate between United States dollars and Canadian dollars are
ludmilkaskok [199]

The cost of the gasoline in US dollars is  $53.24.

Exchange rate is the rate at which one currency is exchanged for another currency. In this question, $1 would be exchanged for 1.26 Canadian dollars.

<h3>Conversion of 15 gallons to liters</h3>

In order to convert 15 gallons to liters, multiply 15 by 3.79

15 x 3.79 = 56.85 liters

<h3>Total cost of of 56.85 liters in Canadian dollars </h3>

56.85 liters x C$1.18 = C$67.083

<h3>Total cost in US dollars</h3>

C$67.083 / 1.26 = $53.24
