Answer:
5 & 8
Step-by-step explanation:
x-y = 3 -> x = 3+y
x+y = 13 = 3+y+y -> 3+2*y = 13
2*y = 10 -> y = 5
-> x = 3+y = 8
Answer:
the answer would be 15/100= .15 *60= 9 so the tip would be 9$

Answer:
Step-by-step explanation:
perimeter=22
AB+BC+AC=22
8+5+AC=22
AC=22-13
AC=9
Apply the Pythagorean theorem:
AB²+AB²=AC²
8²+5²=64+25=89
AC²=9²=81
no it is not a right triangle because it failed the Pythagorean theorem
