Answer:
The center of this circle is at 
. The radius of this circle is 
.
Step-by-step explanation:
A circle with center 
and a radius of 
(
) could be expressed as:
.
(In other words, a point is on this circle if and only if the distance between that point and the center is equal to the radius.)
Rearrange this equation using binomial expansion to match the equation given in this question:
.
.
The equation in this question is:
.
Match up the coefficients of 
and 
in the two equations.:
- Coefficient of :
. - Coefficient of :
.
Thus, 
and 
.
The constants of the two equations should also match up:
.
Substitute in as well as and solve for :
.
(since .)
Therefore, the center of this circle is . The radius of this circle is .
Answer:
C. acute angle
Step-by-step explanation:
As you know ,right angle is equal to 90 degrees so half of 90 degrees is 45 degree which is an acute angle (acute angles are the angles which are less than 90 degrees)
Hope this helps and pls mark as brainliest :)
Bisect means cut in half. If m<ABD is 66 degrees, the only thing you need to do is to take 66/2 and your answer is 33 degrees:)
N=4
Remove the parentheses, move the terms, collect like terms,calculate, divide both sides
Answer:
The angle will be "48.7°".
Step-by-step explanation:
In ΔTBO, the given values are:
TB = 6,000 feet
BO = 9,000 feet
Now,
To find the angle,
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒
