Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13

Triangle ASA's congruence theorems can be used in this ptoof
Triangle ABC is a "right" triangle and "scalene" (because no side is equal).
BC^2 = 1^2 + 2^2
(from B(-1,1) and C(0,-1) ; x=|xc-xb|= |0-(-1)| = 1 , y=|yc-yb|= |-1-1| =2)
BC^2 = 1+4
so the measure of BC = √5 ≈ 2.2
