Question

What is the distance between points E and G?

Round to the nearest tenth of a unit

Answer 1

Use Pythagorean theorem!

A^2 + B^2 = C^2

In this case, let's make A = the difference in height, and B= the difference in width.

Since you're looking for C, the distance between the two points, plug in the distance of the height and width! (Without worrying about C

A = 1-9 = -8
However, you can't have a negative height. So use absolute value to get A= 8

Then find the difference in width
B= 7- -2 = 9

Then plug in:
A^2 + B^2 = C^2
8^2 + 9^2 = C^2
145 = C^2

This can be confusing, but to get rid of the ^2 on C, you take the sqrt (square root) of both sides
C = sqrt (145)

Then use calculator
12.041

Round to tenth
12

Hope this helps!

Answer 2
