Answer: a = 8

Step-by-step explanation:

use the equation a^2 + b^2 = c^2

c = 17, b = 15

a^2 + 15^2 = 17^2

a^2 + 225 = 289

a^2 = 64

a = 8

Answer:

a=8

Step-by-step explanation:

Pythagorean Theorem is:

a^2+b^2=c^2

Plug 15 in for b and 17 in for c

a^2+15^2=17^2

a^2+225=289

Subtract 225 on both sides

a^2=64

Take the square root of both sides

a=8

Hope this helped! :)
