Question

help please

Answer 1

I'm gonna try and spell this
Use Pythagorean theorem...oh i got that right
So yeah that's all you need to answer this question.
Do you know pythagorean theorem?

Answer 2

not really i always mess up at one point

Answer 3

Let's do this step by step
First thing you need to know is the formula:
\[c^2 = a^2 + b^2\]
a, b and c are variables for your sides of the triangle
c is your longest side

Is that clear?

Answer 4

More like definition of the tangent

Answer 5

The tangent of an angle in a right triangle is equal to the opposite side length divided by the adjacent side length. In this case:\[\tan{25^{\circ}} = \frac{10}{x}\]Or if you prefer, the cotangent is even more straightforward:\[\cot{25^{\circ}} = \frac{x}{10}\]

Answer 6

uh okay.. thanks

Answer 7

do you get it tho?

Answer 8

not at all..

Answer 9

alright so there's two ways to do this question
You're gonna have to follow along and allow me to sleep sooner

The first way is what he did up there
Tangent relations.
In a triangle you would have three: sine, cosine and tangent

You define these relations based on your 90 degree angle

Answer 10

so for sine relations it is
sin(your angle) = opposite/hypoteneuse

cosine relation is:
cos(your angle) = adjacent/hypoteneuse

tangent relation is:
tan(your angle) = opposite/adjacent

Answer 11

Do you know what i mean by opposite, adjacent and hypotenuse?
