Approximate the value of each expression shown. Explain your reasoning.
a.√ 38
b. √ 79

a.√ 38  =

b. √ 79 =

Step-by-step explanation:

Here we have , to find Approximate value of each expression shown.

We know that , A square root of a number is a value that, when multiplied by itself, gives the number.  Example: 4 × 4 = 16, so a square root of 16 is 4.  Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root.  Example: √36 = 6 (because 6 x 6 = 36)

a.√ 38

We know that value of √36 = 6 , and here we have √ 38 which value will be slightly greater then 6 Let's find out:

⇒

⇒

b. √ 79

We know that value of √81 = 9 , and here we have √ 79 which value will be slightly less then 9 Let's find out:

⇒

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
