If in a triangle ABC, right angled at B, s-a=3, s-c=2, then the values of a and c are respectively

If triangle ABC is right angled at C, then the value of sec (A+B) is

In triangle ABC, right angled at B, AC = 20 m, /_C=45^@ , find the value of AB.

if in triangle ABC right angled at C then tan A+tan B

The points A(2,9),B(a,5),C(5,5) are the vertices of a triangle ABC right angled at B Find the value of a and hence the area of ABC.

If in a triangle ABC, right angle at B,s-a=3 and s-c=2, then a=2,c=3 b.a=3,c=4 c.a=4,c=3 d.a=6,c=8
