AB = 5 cm
BC = 12 cm
Base = 12 cm
Perpendicular = 5 cm
Hypotenuse = sqrt ( 12^2 + 5^2)
= sqrt (144 + 25)
= sqrt (169)
= 13
Now,
Sin B = P / H = 5 / 13
Cos B = B / H = 12 /13
Tan B = P /B = 5 / 12
BC = 12 cm
Base = 12 cm
Perpendicular = 5 cm
Hypotenuse = sqrt ( 12^2 + 5^2)
= sqrt (144 + 25)
= sqrt (169)
= 13
Now,
Sin B = P / H = 5 / 13
Cos B = B / H = 12 /13
Tan B = P /B = 5 / 12
