Hii friend,
Sin@ = 4/5 = Perpendicular/Hypotenuse
P = 4 , H = 5 , B = ?
By using Pythagoras theroem,
(H)² = (B)² + (P)²
(B)² = (H)² - (P)²
(B)² = (5)² - (4)²
(B)² = 25-16
(B)² = 9
B = ✓9 = 3 .
THEREFORE,
Sin@ = Perpendicular/Hypotenuse= 4/5
Cos@ = Base/Hypotenuse = 3/5
Tan@ = Perpendicular/Base = 4/3
Sec@ = Hypotenuse/Base= 5/3
Cosec@ = Hypotenuse/Perpendicular = 5/4
Cot@ = Base/Perpendicular = 3/4.
HOPE IT WILL HELP YOU... :-)
