jhonyy9 (jhonyy9):

what is the question there ?

OpenStudy (cakecup2018):

I attached a file with the diagram

OpenStudy (cakecup2018):

I already have B which equals 48.5

OpenStudy (cakecup2018):

I just need help solving for a and c

jhonyy9 (jhonyy9):

on this image just there is a right triangle with sides a,b and c with angle C = 90 degrees

OpenStudy (cakecup2018):

oh sorry about that given A= 41.5 and b=20

OpenStudy (hiuto_prayhulla):

you must use the pythagorean theorem..

jhonyy9 (jhonyy9):

do you know the law of sin or cos or tan or cot ?

jhonyy9 (jhonyy9):

this theorem you can using than you know two length of sides but in this case you know just the length of side b

OpenStudy (cakecup2018):

jhoney.. my teacher said i can input sin, cos, tan in my calculator to find the missing crap.. so i just need help about how to input it int the calculadora

OpenStudy (hiuto_prayhulla):

heres some tips you should refer to... In any right angled triangle, for any angle: The sine of the angle = the length of the opposite side. the length of the hypotenuse. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse. The tangent of the angle = the length of the opposite side. the length of the adjacent side.

OpenStudy (cakecup2018):

@jhonyy9 can u come back please

OpenStudy (hiuto_prayhulla):

im here

OpenStudy (cakecup2018):

OpenStudy (hiuto_prayhulla):

type in cos45

OpenStudy (cakecup2018):

okk

OpenStudy (hiuto_prayhulla):

then divide A= 41.5 with b=20

jhonyy9 (jhonyy9):

first of all you ve learned about law of sin or cos ?

OpenStudy (hiuto_prayhulla):

and multiply it with the cos of 41.5

OpenStudy (hiuto_prayhulla):

sorry i meant 41.5 not 45

OpenStudy (cakecup2018):

yes i have learned it
