The line of reflection that would map ABCD onto itself is the line of the diagonal which is -3x + 3y = 9
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The line of reflection that would map ABCD onto itself is the line of the diagonal. The diagonal passes through A(-3, 0) and C(-1, 2), hence:
y - 0 = [(2 - 0)/(-1-(-3))](x - (-3))
y = x + 3
-x + y = 3
-3x + 3y = 9

You can see that each next number is 52 more than previous number, so the recursive formula is
2x+15+x+20+30+25=180
3x+90=180
x=90/3
x=30
New angles
75,50,55
The smallest angle is 50
Answer:
c=5 square root 2
Step-by-step explanation:
a^2 +b^2 = c^2
25 + 25 = c^2
c^2 = 50
c = 5 square root 2
