The amount of money invested at 12% was $4327 while $1442 was invested at 7%.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount invested at 12% and y represent the amount invested at 7%, hence:
x + y = 5679 (1)
Also:
0.12x = 0.07y + 407.5 (2)
From both equations:
x = 4327, y = 1442
The amount of money invested at 12% was $4327 while $1442 was invested at 7%.

Answer:
angle 1 is 42
angle 2 is 138
angle 3 is also 42
Step-by-step explanation:
for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal
for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces
for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42
