Answer:
see below
Step-by-step explanation:
let x = big number
let you = small number
x + y = 215-------> (1)
x - y = 137 ------>(2)
(1)
x = 215 - y ----->(1)
substitute 1 into 2
215 - y -y = 137
-2 y = 78
y = 39
substitute y = 39 into (1)
x = 215 - (39)
x = 176
thus the numbers are 176 & 39

Answer:
t2 = 2.8 hours
Step-by-step explanation:
The distance is the same for each velocity.
Formula
d1 = d2
d = r*t
Givens
r1 = 140 miles / hour
t1 = 3.2 hours
r2 = 160 miles / hour
t2 = ?
Equation
r1*t1 = r2 * t2
Solution
140 * 3.2 = 160 * t2
448 = 160* t2
448 / 160 = t2
t2 = 2.8 hours
corresponding angles are equal
x=123°
