Question

of sin =4/5 then find all other trigonometry ratios.?

Answer 1

Hey dear here is your answer ......

sin=perpendicular /hypotenous
4=perpendicular and 5=hypotenous

To find all other trigonometric ratio we have to find base
By Pythagoras theorem

base will be 3

cos=3/5
sec=5/3
cosec=5/4
tan=4/3
cot=3/4

hope it may help u !!!!!

Answer 2

Heya!!Here is your answer friend ⤵⤵

From the pic ,

Sides of the triangle are 3 , 4 and 5cm.


$sin \: a = \frac{ 4}{5} \\ cosec \: a \: = \frac{1}{sin \: a \: } = \frac{5}{4} \\ cos \: a \: = \frac{b}{h} = \frac{3}{5} \\ sec \: a = \frac{1}{cos \: a} = \frac{5}{3} \\ tan \: a = \frac{sin \: a}{cos \: a \: } = \frac{4}{5} \times \frac{5}{3} = \frac{4}{3} \\ cot \: a = \frac{1}{tan \: a} = \frac{3}{4}$
Hope it helps you ✌✌
