Question

In triangle ABC, angleA = 90°. If AB = 7cm and BC - AC = 1 cm, find : (i) sin C (ii) tan B

Answer 1

let AC be x then BC the hypo is X+1

solving using pyth theorem AB=7 given

BC is 25 ; AC is 24

Sin c is 7/25; tan B is 24/7

Answer 2

In triangle ABC, angleA = 90°. If AB = 7cm and BC - AC = 1 cm,
