2a + c = 1850
2a + c (-c) = 1850 (-c)
2a = 1850 - c
2a/2 = (1850 - c)/2
a = 925 - (c/2)
hope this helps
Answer:
4/3
Step-by-step explanation:
I used a site and my calculator
Area of a sector: 1/2r^2 theta
Need theta
Let x be theta for now
42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians
Radians => degrees is 1.57 * 180/pi or roughly 90.
Answer:
4 units
Step-by-step explanation:
we know that
The <u><em>Intersecting Chord Theorem</em></u> states that: When two chords intersect each other inside a circle, then the products of their segments are equal.
do
In this problem

substitute the given values

solve for x

therefore
The length of segment AY is 4 units
