@just_one_last_goodbye could I use SIN on my calculator to solve this?
OpenStudy (just_one_last_goodbye):
Bible says SIN is against God... so please dont make the Calculator sin :)

@wolf1728 do you know which button I'm referring to?

To solve tat it has to be done in steps:
I'd say first solve for the height by
sine 30 = height/34
height = sine 30 * 34
OpenStudy (wolf1728):
By the way, if you need a trig calclator - here's a very good one.

I got 17 when i typed in my calculator
OpenStudy (wolf1728):
17 is right
sin 34 = .5
and *34 it is 17
OpenStudy (wolf1728):
The "left" side of y also = 17
OpenStudy (wolf1728):
From Pythagoras, we know
x^2 = 17^2 + 17^2
x^2 = 578
and x = ???

OpenStudy (wolf1728):
Pythagoras says you're wrong
if x^2 = 578 then x = ??
OpenStudy (shaleiah):
2?
OpenStudy (shaleiah):
578/289
OpenStudy (wolf1728):
the square root of 578

Yes !!!

OpenStudy (wolf1728):
We need to solve for y
cosine 30 = adjacent / hypotenuse
adjacent = cosine 30 * 34
adjacent = ???

OpenStudy (wolf1728):
Do you know the cosine of 30 degrees
(you may use my calcuator)

OpenStudy (wolf1728):
cosine 30 = 0.86603
34 * 0.86603 = 29.44502
Very good !!!
OpenStudy (wolf1728):
NOW to get "y" we have to add the left side and the right side to get ???

OpenStudy (shaleiah):
I had to switch modes on my calculator.

Alright.... 17+29.44502=46.4 (rounded) :)
OpenStudy (wolf1728):
Wouldn't "y" equal the "left" side 17
plus the right side 29.44502
OpenStudy (wolf1728):
Very good !!
OpenStudy (shaleiah):
Awesome. x=24.0 (rounded) y=46.4 (rounded)
OpenStudy (wolf1728):
So, I guess the answer is "d"?
