The formula for arc length is s=r*angle theta where s is the arc length, r is the radius, and angle theta is central angle formed by the arc in radians.
In this case, the angle would be s/r or 4.2/4 which is 1.05 radians. We have to convert this into degrees and so you would multiply 1.05 by (180/pi) which results in approximately 60 degrees. Remember, if you want to convert radians into degrees, the conversion factor is 180/pi and for degrees into radians, it is pi/180.
Perpendicular line : m × m1 = -1
from y =2x-3 , m=2
m1•2 = -1
m1 = -1/2
substitute P in --> y= mx +c
5 = -1/2 (-6) + c
5-3 = c
c = 2
y = -1/2x - 1
Answer:
Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle. So, ABCD is a cyclic Quadrilateral.
Opposite angles of cyclic quadrilateral are supplementary.
Therefore,
Answer:
x = 20
Step-by-step explanation:
x/10 = 2
Multiply each side by 10
x/10 * 10 = 2*10
x = 20
