Answer:
a=8
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
Hope this helped! :)
Answer: a = 8
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
