Answer:
16 cm
Step-by-step explanation:
We have to first find the radius of the circle.
The area of a sector is given as:

where α = central angle of the sector = 120°
r = radius of the circle
Therefore:

The diameter of a circle is twice its radius, therefore:
D = 2 * 8 = 16 cm
The diameter of the circle is 16 cm
Step-by-step explanation:

and,

represents perpendicular lines.
Two lines are perpendicular when product of their slopes = -1
In, y =½x+4
m1 = ½
In y = -2x -3
m2 = -2
Now, m1× m2 = ½× (-2) = -1
Answer:
x=7
Step-by-step explanation:
x-1
3x-5
______
4x-6
4x-6= 7x-27
-4x -4x
___________
-6= 3x-27
+27 +27
____________
21= 3x
divide both 21 and 3x by 3
= 
7 = x
