Answer:
(x - 3)² + (y + 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = 
= 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25
He lost 8, so he is at -8, he then gains 15 so add 15 to -8"-8 + 15 = 7
He gains 7 so now add 7 to the total: 7+ 7 = 14
He then loses 4, so now subtract 4 from the total: 14 - 4 = 10
Answer: He gained 10 yards.
Answer:
m∠1=39°, m∠3=51°
Step-by-step explanation:
Angle 3 = 180-(39+90)
180-129=51
Angle 1 = 39 b/c of the corresponding angles.
