Question

In triangle ABC right angle at B,AB=24cm,BC=7cm determine.
(1) sinA,cosA
(2) sinC, cosC​

Answer 1

Answer:

please mark me as BRAINLIEST

Answer 2

Answer:In Δ ABC, right-angled at B

Using Pythagoras theorem

AC² = AB² +BC²  

AC² = 576 + 49 = 625

AC = √635

AC = ±25

Now

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

Sin A =  

=  

CosA =  

=  

(ii) Sin C =  

=  

Cos C =  

=  7by25
