Answer 3

Are you learning trig functions or the ratios of the sides of a 30-60-90 triangle?

Answer 4

yeah

Answer 5

@mathstudent55

Answer 6

If you use trig functions, then look at your figure.
In your triangle, which side is the hypotenuse?

Answer 7

h?

Answer 8

Correct.
A right triangle has a hypotenuse, in our case h, and two legs.
The legs are called adjacent leg and opposite leg.
They are adjacent and opposite with respect to one of the acute angles of the triangle.
We are interested in the 30-deg angle.
With respect to the 30-deg angle, is side 10 adjacent or opposite?

Answer 9

opposite?

Answer 10

Correct.
Opposite means across from.
Side 10 is opposite the 30-degree angle.

Now we see what we have.
We have a 30 degree angle.
We know the opposite leg is 10.
We want the hypotenuse.

Which trig function relates the hypotenuse to the opposite leg?
Do you know SOHCAHTOA?

Answer 11

No i dont lol.

Answer 12

\(\sin A = \dfrac{opp}{hyp} \)

\(\cos A = \dfrac{adj}{hyp} \)

\(\tan A = \dfrac{opp}{adj} \)

Answer 13

Look at the sine, cosine, and tangent ratios above.
Which one relates the opposite leg to the hypotenuse?

Answer 14

sinA

Answer 15

\(\color{red}{\sin A} = \dfrac{\color{red}{opp}}{\color{red}{hyp}} \)

\(\cos A = \dfrac{adj}{hyp} \)

\(\tan A = \dfrac{opp}{adj} \)

Answer 16

Correct.
Now we just write an equation using the sine ratio, and we solve for the unknown.

Answer 17

\(\sin 30^\circ = \dfrac{10}{h} \)

Answer 18

Multiply both sides by h.
Then divide both sides by sin 30 to find h.

Answer 19

\(h \sin 30 ^\circ = 10\)

\(h = \dfrac{10}{\sin 30^\circ} \)

Answer 20

is it 30?

Answer 21

Now use a calculator to do the operation on the right side.
Make sure the calculator is in degree mode.

Answer 22

h is not 30

Answer 23

\(\sin 30^\circ = 0.5\)

Answer 24

What is 10/0.5 ?

Answer 25

20

Answer 26

Good.
Now that you have h, you know two sides of a right triangle.
You can use the Pythagorean equation to find the third side.
You can also use trig.

Answer 27

\(a^2 + b^2 = c^2\)

Answer 28

\(10^2 + g^2 = 20^2\)

Solve for g.

Answer 29

Sorry, but gtg.

Answer 30

is it 10?

Answer 31

The answer?

Answer 32

h=20 and g=\[10\sqrt{3}\]

Answer 33

Thans and whats ?

Answer 34

^^^^ thats another question
