Step-by-step explanation:
The two angle measures are equal (which is the point of an angle bisector), so you have
y + 30 = 3y - 50
30 = 2y - 50 . . . . . . . . subtract y
80 = 2y . . . . . . . . . . . . add 50
40 = y . . . . . . . . . . . . . .divide by the coefficient of y
The value of y is 40.
(2 + x + x) / 3 = 22
2 + x + x = 66
2x = 64
x = 32
The numbers are:
2 32 and 32
(2 + 32 + 32) / 3 = 22
66 / 3 = 22
Correct!!
Central angle = 3π / 4 radians
Length of the arc = (3 π / 4) (radius) = 45 in
=> radius = 45 in * 4 / (3π) = 45 * 4 / (3 * 3.14) in
radius = 19.1 in
Answer: 19.1 in
