Triangle abc has perimeter 22cm
ab=8cm
bc=5 cm
by calculation deduce whether triangle abc is a right-angled triangle

AC = 22 - (8+5) = 22 - 13 = 9

 9^2 + 13^2 = 81 +169 = 250

 22^2 = 484

 So no, ABC is NOT a right triangle because the pythagorean thoerem fails

Hope this helps :)

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
