what is the sine, cosine, and tangent ratios for ∠ A.

i wont give u the answer
but i will help you

ok that is what I wanted

first of all we need to use cosine since were dealing with adjacent/hypotenuse

what we first want to do tho is use tangent to find the length of the hypotenuse

actually for the hypotenuse we could do a^2=b^2=c^2

the length is about 170

But he need to find the angle

not the hypotenuse

begzat

to find the angle you need to find the hypotenuse

no

yep

169.78 is the length of the hypotenuse

the hypotenuse is 170 so we dont need to find it

do you know what is Trigonometric Ratios

alright then from there is pretty simple

i rounded

if you know Trigonometric Ratios formula you can find very easy the angle

ok but what are the steps i forgot

okay i will post the formulas and you will find wich one you need to use

ok

sin=opposite leg/ hypotenuse
cos=adjacent leg/hypotenuse
tan=opposite leg/ adjacent leg

know which one you need to use

now***

so I need to use cosine

no because you know opposite and adjacent leg

i also know hypotenuse it is 170

but on the question it said that you know opp. and adj.

you can use tan if you want

I forgot to post the hypotenuse

okay so you can use all

but which one helps me find my angle

all

you can use tan=opp./adjacent leg

well can you help me with the steps for cos
