It can affect a person in many different ways they can measure the slope and find out the slope but they will never be able to measure the whole thing
Answers + Explanation:
1. x + 7 =10
if you know some number + 7 is 10, you know that number must be 3.
so, x = 3
the other way you can solve this would be:
x + 7 = 10
subtract 7 from both sides of the equation
x + 7 - 7 = 10 - 7
x = 3
2. Use the same strategy:
x - 8 = -5
add 8 to both sides of the equation
x - 8 + 8 = -5 + 8
x = 3
3. x + 3 = 6
subtract 3 from both sides of the equation
x + 3 - 3 = 6 - 3
x = 3
4. x + 6 = 3
subtract 6 from both sides of the equation
x + 6 - 6 = 3 - 6
x = -3

Answer:
AB is parallel to BE because it is an equilateral triangle.
BE is parallel to EC because it has 2 of the same angles to the same sides are equal.
Hope that helps, it's a tad hard to explain
