Question

Please answerrrrrrrrrr pleaseeeeeeee

Answer 1

`\Huge\boxed{x=53}`

Explanation:

Hello There!

Once again we need to use trigonometry to solve for X

Here are the Trigonometric Ratios:

Sin = Opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = Opposite divided by adjacent

We are given the adjacent side of x (45) and the hypotenuse (75) so we need to use cos

Remember cos = adjacent divided by hypotenuse

Now we create an equation

`cos(x)=(45)/(75)\\(45)/(75) =.6`

now we have

`cos(x)=.6`

like always we want to get rid of cos

to do so we take the inverse of cos (arccos^-1) and apply that to each side

`arccos^-^1(cos(x))=x\\arccos^-^1(.6)=53.13010235`

finally we round to the nearest degree

we're left with x = 53
