Question

In ΔABC right angled at B, AB = 24 cm, BC = 7 m. Determine:

sin C, cos C

Answer 1

ΔABC is right angled at B

AB = 24cm, BC = 7cm.

Let ‘x’ be the hypotenuse,

By applying Pythagoras

AC² = AB² + BC²

x² = 242 + 72

x² = 576 + 49

x² = 625

x = 25

For Sin C, Cos C

sin C = `("AB")/("AC") =  24/25`

cos C = `("BC")/("AC") = 7/25`
