Evaluate tan(cos^-1 3/5) and assume that all angles are in Quadrant I.

lorasvet [3.4K]

Answer:

Option c

Step-by-step explanation:

We assume that the angle is in the first quadrant.

Observe the attached image.

if $u = cos ^{-1}(\frac{3}{5})$

So:

$cosu = \frac{3}{5}$

By definition:

$cosu= \frac{adjacent}{hypotenuse}$

So:

adjacent side = 3

hypotenuse = 5.

Observe the attached image

We find the opposite side "x" using the Pythagorean theorem.

$x=\sqrt{5^2 -3^2} \\x = 4$

Then, for the angle u:

$tanu = \frac{opposite}{adjacent}\\\\tanu = \frac{x}{3}\\\\tanu = \frac{4}{3}$

The area of a square room is 125 square feet. To the nearest foot, what is the length of one side of the room?

ozzi

Answer:

Side = $5\sqrt5\ \text{feet}$

Step-by-step explanation:

Given that,

Area of a square room is 125 square feet

We need to find the length of one side of the room.

The area of a square shaped room is given by :

$A=x^2$

Where, x is side of the square room

$x=\sqrt{A} \\\\x=\sqrt{125}\\\\x=\sqrt{5\times 5\times 5}\\\\x=5\sqrt5\ \text{feet}$

So, the side of the room is $5\sqrt5\ \text{feet}$ .

4/7m = 2/7( 2m+1 )<br> What is M?<br> Check Solution

aev [14]

4/7m = 2/7(2m + 1)
4/7m = 4/7m + 2/7
4/7m - 4/7m = 2/7
0 = 2/7 (incorrect)

no solution
