Answer 2

Gɪᴠᴇɴ:-If sin A = 3/4, then cos A and tan A are equal to what?

GIVEN DATA

sin A =3/4

ᴛᴏ ғɪɴᴅ :- cos A, tan A

Sᴏʟᴜᴛɪᴏɴ:

Fᴏʀᴍᴜʟᴀ:

⇒sin A =3/4 =height/hypotenuse then

⇨height =3, hypotenuse =4 find another side

⇨hypotenuse^2=length^2+height^2

Aʀᴛʜɪᴍᴇᴛɪᴄ Sᴏʟᴜᴛɪᴏɴ:

⇒4^2=3^2+length^2

↦16=9+length^2

√7=length

• ғɪɴᴅ ᴄᴏs ᴠᴀʟᴜᴇ

•then cos A=length/ hypotenuse

•cos A=√7/4

•ten A =height/length

•ten A=3/ √7 follow link solution easy

Fɪɴᴀʟʟʏ , ᴀɴsᴡᴇʀ ɪs

• =A=3/ √7
