I have an opposite leg of a right triangle that is 40mm long, I have an adjacent leg of 165mm what is the measure of angle a which is the angle in between the hypotenuse and the adjacent leg
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
what is the sine, cosine, and tangent ratios for ∠ A.
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
i wont give u the answer but i will help you
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
ok that is what I wanted
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
first of all we need to use cosine since were dealing with adjacent/hypotenuse
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
what we first want to do tho is use tangent to find the length of the hypotenuse
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
actually for the hypotenuse we could do a^2=b^2=c^2
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
the length is about 170
 one year ago

begzatBest ResponseYou've already chosen the best response.0
But he need to find the angle
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
to find the angle you need to find the hypotenuse
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
169.78 is the length of the hypotenuse
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
the hypotenuse is 170 so we dont need to find it
 one year ago

begzatBest ResponseYou've already chosen the best response.0
do you know what is Trigonometric Ratios
 one year ago

DingusBrainBest ResponseYou've already chosen the best response.1
alright then from there is pretty simple
 one year ago

begzatBest ResponseYou've already chosen the best response.0
if you know Trigonometric Ratios formula you can find very easy the angle
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
ok but what are the steps i forgot
 one year ago

begzatBest ResponseYou've already chosen the best response.0
okay i will post the formulas and you will find wich one you need to use
 one year ago

begzatBest ResponseYou've already chosen the best response.0
sin=opposite leg/ hypotenuse cos=adjacent leg/hypotenuse tan=opposite leg/ adjacent leg
 one year ago

begzatBest ResponseYou've already chosen the best response.0
know which one you need to use
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
so I need to use cosine
 one year ago

begzatBest ResponseYou've already chosen the best response.0
no because you know opposite and adjacent leg
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
i also know hypotenuse it is 170
 one year ago

begzatBest ResponseYou've already chosen the best response.0
but on the question it said that you know opp. and adj.
 one year ago

begzatBest ResponseYou've already chosen the best response.0
you can use tan if you want
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
I forgot to post the hypotenuse
 one year ago

begzatBest ResponseYou've already chosen the best response.0
okay so you can use all
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
but which one helps me find my angle
 one year ago

begzatBest ResponseYou've already chosen the best response.0
you can use tan=opp./adjacent leg
 one year ago

loser0123456Best ResponseYou've already chosen the best response.0
well can you help me with the steps for cos
 one year ago

DirectrixBest ResponseYou've already chosen the best response.0
>well can you help me with the steps for cos The cosine of an acute angle of a right triangle is the ratio of the length of the leg adjacent to the hypotenuse to the hypotenuse length. cos(A) = 165/169.78 cos(A) = 0.9718459 approx A = ? dw:1362220656246:dw
