Question

5. Find the value of x. Round to the nearest degree.
A) 69
B) 21
C) 20
D) 70

I have at least I think the hypotenuse is 14 and the adjacent leg is 5 but for the opposite leg it's ? and so I don't know exactly how to find if it's SOH CAH TOA. I think its TOA, but I'm not sure, also I need help on starting the equation thing. Please help

Answer 2

You are given two sides of this triangle, and an unknown angle is denoted by "x." What are the names of the given sides?

That info should enable you to select the appropriate trig function and thus to find the unknown angle, x.

Answer 3

Hypotenuse and Adjacent?

Answer 4

I'm confused

Answer 5

Look at the place of the degree x we have two know sides in which we know of the hypotenuse which is 14 like you said and we know an side that is the farthest from the angle which would make it what?

Answer 6

Would it be SOH?

Answer 7

The adjacent side touches the angle - hence the name "adjacent". You don't have an adjacent side.

Yes, SOH since you have the opposite side and hypotenuse

Answer 8

That would be correct ^^

Answer 9

Okay so that would be x/14?

Answer 10

Tell us what SOH stands for. Because that's not at all close.

Answer 11

sin opposite over hypotenuse?

Answer 12

Not quite. Sine of an angle equals opposite over hypotenuse.

Answer 13

Oh okay.. sorry!

Answer 14

What is the angle here?

Answer 15

Right angle?

Answer 16

Well if there wasn't a right angle, this question wouldn't exist.

Read this again:
Sine of an angle equals opposite over hypotenuse.

What is the angle here, in this case? Look at your diagram.

Answer 17

I don't know.

Answer 18

You are given a triangle; two of three sides are marked with their respective lengths, and the unknown angle is marked "x."

What is the length of the side opposite angle x?
What is the hypotenuse of this triangle?
Of the three basic trig functions (sine, cosine, tangent), which one involves "opposite side" and "hypotenuse" and the angle x?

Answer 19

Look at the problem this way: x represents the unknown angle. Your job is to find that angle, x, whether in degrees or in radians.

You must know the definitions of the three basic trig functions, mentioned above, and also be able to identify quickly which one applies when you know the "opp side," the "hyp" and the unknown angle, x.

Answer 20

14 is the hypotenuse, 5 for the opposite one? I'm not sure, and we're using sine
