Answer 1

Answer:

17

Step-by-step explanation:

Pythagoras theorem states that in a right angled triangle, the square of the hypotenuse ( H ) is equal to the sum of the square of the other two sides.

H^2 = B^2 + P^2

=>x^2 = 8^2 + 15^2

=>x^2 = 289

=>x = 17

Answer 2

according to the Pythagoras property

hypotenuse square = height square + base square

X square = 8 square + 15 square

X = ✓8 square + 15 square

X = ✓(8+15)^2

here the whole square will be cancelled with the root and leaves X= 8+15

X = 23
