Which inverse trig function could I use to solve this problem?

Mathematics
1 answer:
Llana [10]3 years ago
6 0

Answer:

Inverse sine

Step-by-step explanation:

Recall the three common trig ratios

Remember SohCahToa

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now let's look back at the question

It asks us which inverse function would we use to solve for angle Z

Looking at angle Z, we are given it's opposite side length and the hypotenuse ( longest side ).

When dealing with the opposite side length and hypotenuse we use trig function sine.

When trying to find the angle we use inverse so we would use inverse sine to find the measure of angle A

damaskus [11]

Answer:

- \frac{1}{2}

Step-by-step explanation:

Given

\frac{x^2y^8}{x^7y^6}

= \frac{y^{(8-6)} }{x^{(7-2)} }

= \frac{y^2}{x^5} , substitute values

= \frac{4^2}{(-2)^{5} }

= \frac{16}{-32}

= - \frac{1}{2}

My sister needs some help with her homework. Can someone lend her a hand?
Neporo4naja [7]

Answer:

600 = 10 x 60

Step-by-step explanation:

If you do 10 x 60 or 60 x 10 it'll equal 600, that's what the questons is looking for so the way it'd be written is:

6 hundreds is 10 times as much as 600.

600 = 10 x 60

Hopefully this helps! I hope you and your sister have a blessed day!

I have been trying to solve problem 5 and 6 for 30 mins​

Answer:

#5

x = 45

E

Step-by-step explanation:

Theorems you need:

  • The measures of 2 adjacent angles that form a straight line with the outer sides add up to 180°.
  • The sum of the interior angles of a triangle add up to 180° ((n-2)×180).

#5

Knowing those, you first want to find the triangle's 3 interior angles.

The angles <QSO & <QSR are adjacent (share a common ray) and form a straight line with the outer rays, therefore they add up to 180.

So m<QSO+m<QSR=180.

Rewrite the equation: m<QSR=180-m<QSO

Plug the known value in: m<QSR=180-(3x-17)

Distribution & Combining like terms: m<QSR=180-3x+17=197-3x

Now solve for the 3 interior angles to equal 180.

(197-3x)+(25)+(2x+3)=180

Combine like terms: 225-x=180

Isolate the x term (-225 to both sides): -x=180-225=-45

Isolate the x (×-1 to both sides):

x=45
