Answer:
The equation of circle is:
Solution:
The general form of equation is given as:
Where, "r" is radius of circle and (a, b) is center of circle
Given that center at (-2, 1)
a = -2 and b = 1
Substitute (a , b) = (-2, 1) and (x, y) = (-5, -3) in general equation
Substitute r = 5 and (a, b) = (-2, 1) in general equation
Thus the equation of circle is found

Step-by-step explanation:
7.38 is 7.5% of 98.4
(7.5 /100 ) x=7.38
so x= 738/7.5= 98.4

Frank -----------------------------------------------Base
Frank - Base = 400 ft
Base- Top statue = 360 feet
Angle of elevation =Angle Top-Franck-Base, let it be angle Ф
tan (Ф) = 360/400 = 0.9
arc tan (0.9) = tan⁻¹(0.9) = 41.98 ,
Ten angle of elevation Ф ≈ 42°
Answer: On a coordinate plane, 2 triangles are formed with a line with points (0, 2) and (x, y). A triangle has a rise of 1 and run of 2. Another triangle has a rise of 3 and run of 6.
