<u>Relations Between Angles</u>
We need to recall some properties of the angles to find the angle marked as O. Please refer to the image attached.
First, if two angles O and P are formed from the intersection of a line with a secant line, their sum is 180°.
From the figure, 
, or equivalently:
Second, if an angle 
is formed by the intersection of two lines, then the same angle will be formed by the intersection of two lines perpendicular to the original lines.
Angle is formed by the intersection of BC and BA. The segment EA is perpendicular to BC and CD is perpendicular to BA, thus the angle P is congruent to the angle .
It follows that
Answer:
Its 22
Step-by-step explanation:
x is 19
so 3+19 is 22
The circumference of the circle is 762π cm.
<h3>What is length of arc of a circle?</h3>
The length of arc a circle can is determined with the radius and central angle of the arc.
The radius of the circle is calculated as follows;

The number of boats are 8; so, he needs a total of 8*126 gallons.
In order to get the partial products, first you have to decompose 126 in its hundreds, tens and ones, that is, 126 = 100 + 20 + 6. Then multiply each of this terms by 8, as follows
8*100 = 800
8*20 = 160
8*6 = 48
Finally you have to add the results of these multiplications, that is, 800 + 160 + 48 = 1008. Therefore, he needs 1008 gallons for all the boats.
