Use trig ratios to solve a.

\[\tan^{-1}(y)=\frac{ 100 }{ 41 }\]

It seems right to me.

now how do i do that ^^ i get NaN when i put it into calculators

Which calc do you have?

You made a mistake.

http://www.rapidtables.com/calc/math/Tan_Calculator.htm thats the calc i used

|dw:1375998733252:dw|

so do i use tan 100/41 or tan ^-1(100/41)

using both i got NaN

im still new to this so im horrible at it

Use this.

Write 100/41 in the first box then click 'atan'.

1.18169909573962

but how can

you are in radian mode

-_- i gotta remember to click degrees

that is too far off... atan(100/41)= ? deg

omg one sec laptop being stupid

I blame it on the loose nut behind the space bar

\[\approx68\]

@phi very funny you are

67.706... deg

@ phi it says to the nearest degree = rounding so
\[\approx68\]

ok

so for part b i think that it does matter which function you use, but im not entirely sure why

it should not matter, unless two of the legs are given with more precision than the 3rd side.

what do you mean with more precision than the third

oh ok

i saw that too but

i wasnt sure on that part of it
