Answer 27

@sbuck98: would you please share all of your work, so that the rest of us will know how you got your results? You may get better feedback that way.

Answer 28

I've been asking someone to step me through this. Can you? I do online school so I've had no lessons on this due to my lack of internet. @mathmale

Answer 29

I just need someone to teach me how to find the angle. I know how to do the last part. Could you explain? @mathmale

Answer 30

Note that this triangle is a right triangle, because one of the angles is 90 degrees.
Because of this fact, you can use the Pythagorean Theorem to find the length of the hypotenuse. Does this vocabulary sound familiar to you?

Answer 31

Your right triangle has two legs (as well as the hypotenuse).

Square the lengths of these two legs.

Sum up those 2 squares.

Find the sqrt of the result.

Mind sharing your work?

Answer 32

The pythagroean theorem is that they're all equal right?

Answer 33

Okay, I got 12 for my sum. and the square root of 12 as 2 sqrt 3

Answer 34

Sorry, no. Better look up Pythagorean Theorem; it's one of the most basic tools in algebra and geometry, also in trig.

Write out the P. Theorem after you've looked it up.

Answer 35

But did you square the lengths of the legs? I think not.
Must do that.

Answer 36

The square of the hypotenuse is equal to the sum of the squares of the other two sides.

Answer 37

How do I square the other two legs when I don't know what they are?

Answer 38

Share your png file. Looks like we're talking about 2 different problems here. Best if you'd please share only one problem per post to avoid this confusion.

Answer 39

Explain what you mean by "but I don't know the lengths of the legs." ??

Answer 40

Review: a right triangle has ONE hypotenuse and TWO legs.

Answer 41

9+3=12, you told me to square the sum.. then the other two legs that I don't know.

Answer 42

What does "sum" mean to you? We have a major misunderstanding here, I'm afraid.

Answer 43

The sum is the total amount.....

Answer 44

And what does "square" mean in this context?

Answer 45

Square root... A perfect square, the square root of 12 is 2 sqrt 3

Answer 46

True, but I asked y ou to square the lengths of the 2 legs, not to find their square roots.

Answer 47

What are the lengths of the 2 legs?

Answer 48

9, and 3.

Answer 49

What is the square of 9? No, not the square root, but the square.

Answer 50

3? isn't squaring & square root the same thing?

Answer 51

Absolutely not.

The square root of 4 is 2. The square of 4 is 16, which is 4 times 4.

Answer 52

oh so it's 81 & 9!

Answer 53

81+9=90

Answer 54

Yes. Now add those two squares together (that is, find their sum).

Answer 55

I did above

Answer 56

Now you'll need to find the length of the hypotenuse. How would you do that?
Important: what is the name of the operator you must apply to 90?

Answer 57

Pythagorean theorem?

Answer 58

You squared 9 to get 81. You squared 3 to get 9. You added these two squares together. Now, you want to find the length of the hypotenuse. What is the opposite of "square"?

Answer 59

sqrt

Answer 60

Yes. What is sqrt(90)?

Answer 61

3 sqrt 10

Answer 62

Yes. That's the length of the hyp.
Find the value of Sqrt(10) using your calculator.

Answer 63

3.16

Answer 64

Now multiply tht by 3.

Answer 65

9.48

Answer 66

Now, how many decimal place accuracy do you want?

Answer 67

3

Answer 68

or 4

Answer 69

4 would be best.

Answer 70

type into your calculator: Sqrt(90). Round off the decimal fraction to 4 places.

Your result?

Answer 71

9.486

Answer 72

That's 3 decimal place accuracy. Thought you wanted 4 decimal places.

Answer 73

That's fine

Answer 74

Satisfied? Learn something helpful?

Answer 75

Yes

Answer 76

Good to work with you. Good luck!

Answer 77

Wait, I still have to find the angle... @mathmale

Answer 78

Can you find the length of the "adjacent side" of the u nknown angle? What is it?

Answer 79

no

Answer 80

An "adjacent side" is the side right next to the angle you're trying to measure. Look at your diagram again.

Answer 81

In other words: Find Angle A. What's the length of the side (Not the hypotenuse) next to Angle A?

Answer 82

and what's the length of the side OPPOSITE Angle A?
