Question

1)Sino =35, find:-
Coso =
tan o =​

Answer 1

Sin a = opposite/hypotenuse

         = 3/5

By pythagoras theorom,

$Adjacent^{2}$ = hypotenuse^2 - opposite ^2

= 5^2 - 3^2

= 25- 9

= 16

Adjacent = $\sqrt{16\\}$

= 4

cos a = adjacent/opposite

         = 4/5

Tan a = opposite/ adjacent

          = 3/4

Therefore, Cos a = 4/5 and Tan a = 3/4
