Answer 2

Answer:

Step-by-step explanation:

let the triangle be abc with angle c =90.

so by the formula costheta=adjacent/hypotenuse

cosa=ac/ab and and cosb=bc/ab

so from given,

ac/ab=bc/ab

cancelling denominator , we get ac=bc

which implies it is an isosceles right angled triangle. so lets the angles be x and x. then apply angle sum property of triangle to get x=45.
