Question

Last trigonometry question.. need help explaining please

Answer 1

I almost got this one.. but I'm confused now!

Answer 2

First I'm doing YXW triangle, not sure if I should use tan, sin, or cos?

Answer 3

you want to find sides XY and XW , right ?

Answer 4

Yes

Answer 5

you have side OPPOSITE to 44 , right >
so what will u use ?

Answer 6

Right, opposite is 5.27 then I have x for side XW, is that side adjacent?

Answer 7

lets first find hypotenuse XY
which trigonometric function will u use ?
you have opposite side...

Answer 8

Tan 44 = 5.27 / x

Answer 9

that will directly give you x= XW :)

Answer 10

x = 5.46?

Answer 11

yes!

Answer 12

now find XY
can you ?

Answer 13

Oh okay, so now we have to make the triangle bigger to XYZ?

Answer 14

XY is just hypotenuse of XYW triangle!

Answer 15

so,, we need hypotenuse and side "opposite" to 44 degree angle
sin 44 = .. ?

Answer 16

sin 44 = .6946

Answer 17

i mean in that triangle
sin 44 = 5.27/XY
got this ?

Answer 18

.6946 = 5.27 / XY
okay got it! i'll work it out

Answer 19

I got XY = 7.59

Answer 20

correct!
so can you find WZ now ?

Answer 21

Do I subtract 5.27 from 7.59? Because that is 2.32 and it's one of the answers :D

Answer 22

XY is radius = XZ
XZ = XW +WZ
so, XY = XW +WZ
WZ = XY-XW = 7.59 - 5.46
you should also know how :)

Answer 23

and yes, 2.32 is correct :)
ask if any doubt in any step :)

Answer 24
