Question

6.If CosX=2/3then Tan x is equal
to​

Answer 1

Answer:

root5/2

Step-by-step explanation:

from pythagoras theorem we can get it simply.

cosx=2/3

means tanx=root5/2

Answer 2

Answer:

√5/2 is the answer because Pythagorastheorem if we caluculate

Step-by-step explanation:

cosx=adj side/hypotonuse

tanx= opp side/ adj side

We know adjacent side and hypotonuse

so, by Pythagoras theorem

hyp square= side square + side square

3²= x²+2²

9=x²+4

x²=9-4

x²=5

x=√5 (opp side)

tanx= √5/2
