Pythagurus

anonymous · Answer

My answer: 8/cosec 35deg

anonymous · Answer

lol he might have been a guru, but it was Pythagoras

shubhamsrg · Answer

why cosec?? it should be "cos"

anonymous · Answer

$$\cos(35)=\frac{8}{?}$$
$$?=\frac{8}{\cos(35)}$$

shubhamsrg · Answer

i mean either 8cos 35 or 8/sec 35

anonymous · Answer

I don't know 1 more length so I can't use pythagoras's theorem. And no-one of the answers have Cos, even though i concluded to that as-well.

anonymous · Answer

then a calculator

shubhamsrg · Answer

if unknown side is x then cos 35 = x/8,,and not 8/x

anonymous · Answer

If Cos isn't an applicable answer it must be something else then, no?

shubhamsrg · Answer

8/(sec 35)

shubhamsrg · Answer

its the same as 8 cos 35

anonymous · Answer

howso?

shubhamsrg · Answer

1/cos x =sec x ..this is basic trigonometry sir..
