We know that ,
SinΦ = Perpendicular / Hypotenuse
⠀⠀⠀= 7 / 25
i.e ,
Perpendicular = 7
Hypotenuse = 25
So , Finding Base by Pythagoras theoram,
AC² = AB² + BC²
25² = 7² + BC²
625 = 49 + BC²
625 - 49 = BC²
576 = BC²
√576 = BC
24 = BC
Therefore , BC = 24
Now Finding Cos Φ and tan Φ ,
Cos Φ = Base / perpendicular
Cos Φ = 24 / 7
