Question

In triangle ABC , right angled at B , AB = 24cm , BC = 7cm. Determine :
1) Sin A , Cos A
2) Sin C , Cos C​

Answer 1

Answer: 1) Sin A =7/25

Cos A =24/25

2) Sin C =24/25

Cos C =7/25

Answer 2

Answer:

1) sinA =7/25

cos A =24/25

 2) cos C = 7/25

sin C = 24/25

Step-by-step explanation:

AB =24cm

BC = 7cm.

AC = ?

AC^{2} =AB^{2} +BC^{2} \\          

 =24^{2} +7^{2} \\          

 =576+49\\        

=625\\

AC=25

 THEREFORE,

1) sinA =7/25

cos A =24/25

 2) cos C = 7/25

sin C = 24/25
