Which equation can be used to find the unknown length, a, in this triangle? A right triangle has a side with length 15 meters and hypotenuse with length 17 meters. The other side is labeled a.
a squared + 15 squared = 17 squared
15 squared + 17 squared = a squared
a squared + 15 = 17 squared
a + 15 squared = 17 squared

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

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

there is no graph so i cant sorry
