Answer:
Radius r = ±√52
Coordinates of center =
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x1, y1) and radius r is given by
(x - x1)² + (y - y1)² = r ²
<u>To find the radius and coordinates of center</u>
It is given that an equation of circle,
(x - 4)² + (y + 6)² = 52
Compare two equations,
we get r ² = 52
r = ±√52
(x - x1)² = (x - 4)² then x1 = 4
(y - y1)² = (y + 6)² then y1 = -6
Coordinates of center = (4, -6)
Complementary angles equal 90 degrees so
The measures of the two angles = 90
(4y +5) + (4y +8) = 90
4y + 4y = 8y and 5 + 8 = 13
90 - 13 = 77
8y = 77
77/8 = 9 5/8
y = 9 5/8
Now we can plug this into each measyre to find the answer
9 5/8 x 4 = 38.50
38.50 + 5 = 43.50
38.50 + 8 = 46.50
46.5 + 43.5 = 90
The first angle measures 43.5
The second angle measures 46.5
I hope this helps!
Consecutive integers = in this situation double-digit whole numbers
So as there are 3 of them let's say 2 are 11 because that would be the highest consecutive number so 11+11= 22 and 48-22=26 so the three have the ages of 11,11,26 and the oldest would be 26 ;)
