Question

in ∆abc , right angled at B,AB=24cm, BC=7cm. determine
1) sin A,cosA
2)sinC,cosC​

Answer 1

Answer:

1.SinA=7/25 COSA=24/25

2. SinC=24/25 COSC=7/25

Step-by-step explanation:

Draw a right angled abc

Using pythagoras theorem

AC SQUARE = AB SQUARE + BC SQUARE

AC SQUARE = 24 SQUARE + 7 SQUARE

= 576 + 49

= 625

AC = 25

1. SINA=P/H=7/25

COSA=b/h=24/25

2. SinC=p/h=24/25

COSC=b/h=7/25
