Question

Which equation can be used to find the unknown length, a, in this triangle?

Answer 1

Answer:

Solution :-

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

Answer 2

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
