Answer:
<h2><u>Solution </u><u>:</u><u>-</u></h2>
We know that
Base² + Length ² = Hypotenuse²
(a)² + (15)² = 17²
So,
Option A is correct
If we solve it
(a)² + 225 = 289
(a)² = 289 - 225
(a)² = 64
a = √{64}
a = 8
9514 1404 393
Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
