Question

Find x.

Answer 1

\[\tan \theta = \frac{opp}{adjacent}\]

Answer 2

tan 75= 125/x

Answer 3

Can you solve it from here? :o)

Answer 4

x=33.51

Answer 5

is that right? :)

Answer 6

33.5

Great job!! :o)

Answer 7

thank you so much!!! can you help me solve for y?

Answer 8

I can try :o)

Answer 9

thanks :)

Answer 10

Well we know x is 33.5, so you could use Pythagorean theorem to find y. :o)

Answer 11

oh okay let me try to figure that out :)

Answer 12

wait i thought x was the hypotenuse, is it?

Answer 13

it cant be if its less than 125 though

Answer 14

Hmmm, good point. :/

Answer 15

so we must be wrong about x :(

Answer 16

Maybe try to solve for y first instead?

Answer 17

oh okay, do u know how i would do that?

Answer 18

cos 75=y/125

Answer 19

to find the x do it Sin(75)=125/x cross multiply
to find y do it tan(75)=125/y

Answer 20

thanks :) @begzat

Answer 21

can you solve or not ?

Answer 22

yes 1 moment

Answer 23

x=128.9 is that right?

Answer 24

and y=33.5?

Answer 25

x=129.4

Answer 26

oh ok my fault i redid it and got that

Answer 27

y is right

Answer 28

thank you!! how did you know whether to use tangent or sine?

Answer 29

Sine=Opposite leg/Hypotenuse

Cos= Adjacent leg/Hypotenuse

Tan=Opposite leg/Adjacent leg

Answer 30

right

Answer 31

you have to remember this :)

Answer 32

oh i see so you got it from the information given

Answer 33

i know SOHCAHTOA i just didn't see what they gave us for a second sorry
