Question

In the above figure AD = 14 units ; BC = 5 units ;

Answer 1

Answer:

Answer:1)12/13

2)5/12

3)13/5

Step-by-step explanation:

ABC is right angled triangle where AC=13 and BC=5 therefore AB=12 by pythagoras theorem .AB=\sqrt{13^{2}-5^{2} }

13

2

−5

2

. phi is angle BAC.Therefore cos phi=12/13.

tan phi=5/12

cosec phi=13/5
