Question
In a right triangle, one side is 19 m, the second side is 20 m. Find the hypotenuse.
Hint:
Pythagoras theorem states that if a triangle is right angled then the square of the hypotenuse is equal to the sum of the squares of other two sides.
The correct answer is:
Here, we have to find the hypotenuse.
In a right triangle, the two other sides are 19m and 20m.
We have, h² = 19² + 20²
Or, h² = 361+400
Or, h = √761 m.
Hence, the correct option is (A) .
TThe pythagoras theorem is expressed as h2 = p2 + b2 ,where h is the hypotenuse and p &b are the other two sides.
