Question

if angle abc right angled at b a b equals to 24 cm BC equals to 7 cm determine Sin A cos a sin C cos C cos c ​

Answer 1

Answer:

In Δ ABC, right-angled at B

Using Pythagoras theorem

AC² = AB² +BC²  

AC² = 576 + 49 = 625

AC = √625

AC =  25

(i) In a right angle triangle ABC where B=90° ,

Sin A = 7/25

CosA = 24/25

Sin C = 24/25

Cos C = 7/25
