Question

Refer to the triangle below. If a = 4 and b = 6, solve for c. show work Also, give the unsimplified radical form answer and then the decimal form answer rounded to the nearest hundredth.​

Answer 1

Look at the image below where I labeled the sides

To solve this you must use Pythagorean theorem:

`a^(2) +b^(2) =c^(2)`

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 4

b = 6

c = unknown

^^^Plug these numbers into the theorem

`4^(2) +6^(2) =c^(2)`

simplify

16 + 36 =
`x^(2)`

52 =
`x^(2)`

To remove the square from x take the square root of both sides to get you...

√52 = x

^^^Unsimplified radical

2√13

^^^Simplified radical

7.21

^^^Rounded to hundedths

Hope this helped!
