5sinA=4, find the value of tanA.​
NARA [144]

Answer: tan A=4/3

Step-by-step explanation:

Áp dụng định lí py ta go ta đc:

5^2=4^2+x^2

I need the formula not the answer thanks<br><br>x^{2} [/tex]&gt;49
sladkih [1.3K]
X²>49
well, I don't know a formula but this is how I would solve it
I first solve x²=49 to obtain x=+/-7

so then would it be x>+/-7?
if we try 8 it works
if we try -9 it works

so answer is x>+/-7
basically x<-7 or x>7
