in triangle ABC , angle B is a right angle. AB+30 and Sec A=5/3. find each value in fraction and decimal form
sin a =4/5
ok but how did you get that
|dw:1369794012893:dw| here sec a=hyppoteneus/adjacent so hp=5 and adj=3 so opposite side =4 by pythagorus thm so sin a=opposite/hypp=4/5
its sin A
isnt sin opposite/ hypotenuse
you said sec A=5/3 so the sec=hyp/adj. the hyp=5 and the side adjacent to angle A would be adjacent. Through pythagorean theorem you can find the other value because it is a right triangle
in the pathagorema theorem what values go with what is a=5 and c=3?
i know that but i need to show work so what goes where
does a=3 c=5?
(hypo)^2=(side 1)^2 +(side 2)^2
@chrisplusian can you help me with one more
sam thing but with these values
The trick with pythagorean theorem is that the "c" is always the hypotenuse
Csc=Hyp/opp so the opposite side from angle C is =3 and the hypotenuse is =5. so csc C =5/3
Hope that helps @lala2
yes it does alot! thanks soo much!
no problem I have to do some studying now so good luck
ok thanks again!
