geometry help on right triangles and trigonometry

OpenStudy (anonymous):

OpenStudy (rea201):

You will be using the Pythagorean Theorem to solve this problem. The Pythagorean Theorem is c^2=a^2+b^2 the little leg, 3, is a. The large leg, 4, is b. And c is the hypotnuese which we are trying to find.

OpenStudy (rea201):

do you get that

OpenStudy (anonymous):

c^2=23

OpenStudy (anonymous):

am i right

OpenStudy (anonymous):

what is the next step

OpenStudy (rea201):

c^2=25 be 3^2=9 and 4^2=16. But now you will find the square root of 25.

OpenStudy (anonymous):

ohh so its 5

OpenStudy (rea201):

Yes you are correct

OpenStudy (anonymous):

is it D

OpenStudy (rea201):

it is c

OpenStudy (anonymous):

can you help me with a couple more

OpenStudy (rea201):

sure you want to message them to me

OpenStudy (anonymous):

OpenStudy (rea201):

ok so for this problem we will use the same formula.Can you tell me what b and c are

OpenStudy (anonymous):

b=10 and a =8 right

OpenStudy (rea201):

actually 10 is the hypotnuese so c=10 and b=8. We are trying to find the small leg, a. I have drawn a triangle as how you should look at it when doing these type of problems.|dw:1383246094477:dw|

OpenStudy (anonymous):

so im stuck i got 100=a^2+64 am i right

OpenStudy (rea201):

yes so now you will subtract 64 off off the left hand side and then find the square root.

OpenStudy (anonymous):

so its 6 C omg ur the best tutor ever i never thought that i could do this

OpenStudy (anonymous):

i have this other one its harder ok

OpenStudy (rea201):

Thanks and you are correct it is c

OpenStudy (rea201):

and ok go right ahead

OpenStudy (anonymous):

OpenStudy (anonymous):

i tryed it and this is wht i got 44=a^2 but there is not squar root of 44

OpenStudy (rea201):

ok one sec let me take a look

OpenStudy (anonymous):

is it A
