The ratio of OC to OA is OC/ 10√2 - OC
<u>Explanation:</u>
Given -
AD = 4 cm
M is the midpoint of CD
Ratio of OC to OA = ?
In a square, all the interior angles are 90°
Therefore,
ΔADC, ΔABC and ΔBCM are right angled triangle
AC is the diagonal which divides ∠DAB and ∠DCB equally
If AD = 4 cm, then AB, BC and DC are also 4cm
In ΔADC,
(AC)² = (AD)² + (DC)²
(AC)² = (10)² + (10)²
AC = 10√2 cm
AC = OA + OC
OA = AC - OC
OC/OA = OC / AC - OC
OC / OA = OC / 10√2 - OC
Therefore, the ratio of OC to OA is OC/ 10√2 - OC
<span>As you look at the graph from left to right (increasing x), if the line is going up(increasing y), slope is positive.
.
If it's going down (decreasing y), slope is negative.

1. is 450ft, and #2. is 64ft.
Answer:
x is 12
Step-by-step explanation:
You can find x two different ways.
The first way is to look at the numbers on the left side. You need to find the scale factor used to get from 4 to 6.
4 x 1.5 = 6
Use this for the 8
8 x 1.5 = 12
The other way you can use is look at the number on the top triangle. You need to find the scale factor used to get from 4 to 8.
4 x 2 = 8
Use this for the 6
6 x 2 = 12
