Question

3. (a) In AABC, right-angled at B, AB = 24 cm, BC = 7 cm. Determine:
(1) sin A, cos A (ii) sin C, cos C.
b) If triangle ABC is right-angled at B and AB = 12 cm, BC = 5 cm, fin
​

Answer 1

Answer:

Step-by-step explanation:

In triangle ABC,

AB=24cm,BC=7cm

So,AC=root 24^2 +7^2

=root576+49

=root625

=25cm

Thereforei) sinA=7/25

...... cosA=24/25

ii) sinC=24/25

cosC=7/25(ans)
