Answer 1

Answer:

Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

Using Pythagoras theorem

Hypotenuse² = Perpendicular² + Base²

17² = 8² + x²

x² = 17² - 8²

x² = 289 - 64

x² = 225

x = √225

x = 15

Answer 2

AC =15

Step-by-step explanation:

The given triangle is a right angled triangle.

AB is the hypotenuse and BC &AC are the two sides of the traingle.

So,AB² = BC² + AC². (Pythagoras theorem)

(17)² = (8)² + (X)²

(17)²-(8)²=(X)²

(X)² = 289 - 64

(X)² = 225

X= 15. (Taking square roots of both the sides)
