is it right angled triangle
Answer:
a = 15 and b = 17
Step-by-step explanation:
Since triangle ABC is right angled at B ,by pythagoras theorem 8^2 + a^2 = b^2
a^2 -b^2 = -64
(a + b ) (a - b ) = -64
We have a + b = 32____(1)
So a-b = -2______(2)
Add 1 and 2 then
2a = 30 and a = 15
Substitute a in 1
b= 32 - 15 = 17
