Answer:
Step-by-step explanation:
<u><em>Part B:</em></u>
The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.
<u><em>Part C:</em></u>
Coordinates of the midpoint of line BC ( y = - 1 ) are
( 
, 
) = <em>( - 2 , - 1 )</em> and the equation of the line ⊥ to BC is <em>x = - 2</em>
Because BC is ║ to x-axis and m∠A is 90° , the center of the circle is midpoint of BC and r = 
= 4
Answer:
A.4x+2
Step-by-step explanation:
distrubuve property,u multiply the numbers in the bracket by two.so,2x2=4 and 2x1=2 so 4x+2
The rate of change is 1/2 as it is increasing by 50 per week
Answer:
135%, 74%
Step-by-step explanation:
a. 540/400=1.35=135%
b.400/540=.74=74%
Answer: The answer for x is 32 degrees while y is 35.
Step-by-step explanation: The reason for this is because two lines right across each other are vertical and are equal. For example 32 degrees is across x therefore x equals 32 degrees also. The way we find y is by subtracting all the other angles and then finding the measurement of the angle. The equation would look like this 180-90-32-23=35. We got the 90 degrees from the angle O because it is right across a 90 degree angle there making it equal to the other angle. Hope this helps and thank you for brainliest!
