Answer:
See explanation
Step-by-step explanation:
The given circle has center O.
A, B,C, and D are points on the circumference of the circle.
We want to prove that: 
We need to join to B and C as shown in the attachment.
Recall that angle subtended by arc BC at the center is twice the angle subtended at the circumference by the same arc.
This implies that:
The LHS of equation (1) and (2) are equal. Therefore the RHS are also equal.
This implies that:
Answer:
Ian
Step-by-step explanation:
this is because you divide the total wage by how many hours each person works for, ian earns 13 dollars an hour, Cody earns 11 dollars an hour, and Cindy ears 12 dollars and 50 cents per hour.
A rational number<span> is any </span>number that can be expressed as the quotient or fraction. It is also a number that does not repeat and/or go on forever (ex. pi or <span>3.1415926535</span><span>)
Soo, the rational number is
the √49
√49 = 7 7 is a rational number, also a whole number as well, how bout that.</span>
It’s called me a few minutes before the meeting so I’m not working for you and
We know that the ocean floor has a depth of 247 ft, and we also know that the diver is<span> underwater at depth of 138 ft, so its distance from the ocean floor will be:
</span>
ft
<span>
Now, the </span>rock formations rises to a peak 171 to above the ocean floor, so to find <span>how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:
</span>
ft
<span>
We can conclude that the diver is 62 feet </span><span>
below the top of the rock formations.</span>
