Answer:

Ur answer

Step-by-step explanation:

it can be concluded from the Euclid's axiom which is- if equal are added to equals the holes are equal

Answer 2

Answer:

Step-by-step explanation:Angle sum property : sum of three angles is 180°

If it is a right triangle then

90°+2x=180

2x=180-90

2x=90

X=90÷2

X=45

Therefore we can conclude that it is a right triangle
