Question

do I use sin, tan, cos for this?

Answer 1

cos

Answer 2

because the opposite is not defined you cant use sine, but you have adjacent and the hypotnuse which means you can use cosine

Answer 3

yep

Answer 4

nop its base/hyp

Answer 5

but you dont have the base therefore you must use cosine

Answer 6

so it should be 2.28/4.07

Answer 7

well i think thats the way it should be done.. maybe you can ask someone else to confirm it.

Answer 8

well no cos function will be use..
adjacent = 2.28 , hyp =4.07

Answer 9

yes.

Answer 10

yes, so you cant do sine because it requires you use adjacent

Answer 11

lol no.. its cosine.

Answer 12

now just look first letter of each word.
S=sin, P= perpendicular, H= Hyp, C=Cos , B= bAse, T=tan

Answer 13

that is a formula for making things easy..
mean when u use sin=perp/hyp
cos= base /hyp , tan =perp/base

Answer 14

base and hypotaneous will be the sides with angle.. and perpendicular is the side opposite of the angle on which we are working.

Answer 15

if we are working on this mark angle then your Hyp base and perp will be this.

Answer 16

if you are working on this angle then your hyp base and perp are this.
