Sector area= 0.5 r^2 * theta (in radians)
arc length = r*theta
3=r*(0.7854)
r=3.82
sector area= 0.5 * (3.82)^2 * 0.7854 = 5.73 sq ft
Answer:
Step-by-step explanation:
In a rectangle, diagonals are equal and bisect each other
BE = AE
6x - 5 = 2x + 7
6x - 2x - 5 = 7
4x - 5 = 7
4x = 7 + 5
4x = 12
x = 12/4
x = 3
AE = 2x + 7
= 2*3 + 7
= 6 + 7
AE = 13
AC = 13 + 13
AC = 26
m∠EBC = 50
In rectangle, each angle is 90
m∠ABE + m∠EBC = 90
m∠ABE + 50 = 90
m∠ABE = 90 - 50
m∠ABE = 40
In rectangle, AB // DC and DB transversal
m∠ECD = m∠ABE { alternate interior angles}
m∠ECD = 40

Answer:
4
Step-by-step explanation:
First you solve for x
3x-1 = 2x-4+2x-3-2
3x-1 = 4x-5
You get 4 = x
substitute 4 for x
2(4)-4
8-4
=4
