Question

if sinA=3/4 then find cosA and tanA

Answer 1

Since sine = opposite / hypotenuse,

then using pythagoras theorem, the sides of the triangle are 3, 4 and root7

Since sin=3/4

cos= root7/4 (adj/ hypo)

tan= 3/root7 (opp/ adj)

Answer 2

=>SinA=3/4

A is the angle.....

3 is opposite to A

Root7 is adjacent to A

4is the hypothesis to A

=>CosA=root7/4

=>tanA=3/root7
