If cos = 3/5, then tan = cramming trying to graduate

The answer is:

or

To find the answer, we first need to find the value of the given angle, we can calculate it since we already know the cosine of that angle.

So, solving we have:

Now, that we know that the angle is equal to 53.13°, we can calculate the value of the tangent, so:

Also, we can find it using the Pythagorean Theorem and the trigonometric identities:

We have that:

So, using the given information we have:

Where,

Hypothenuse, is equal to 5.

Adjacent, side is equal to 3.

So, we are looking for the opposite side.

Then, substituting it into the Pythagorean Theorem formula, we have:

Now that we already know the opposite side, we can find the value of the tangent that will be:

Have a nice day!

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
