C: x = 10
Step-by-step explanation:
PO = QR (so having equal central angles)
Now
4x-11 = 2x+9
4x-2x = 9+11
2x = 20
Dividing both sides by 2
x = 10
Ответ:
x=10
Step-by-step explanation:
2x+9=4x-11
-2x -2x
9=2x-11
+11 +11
20=2x

Alright, lets get started.
Two sides of the rectange are 14 and s.
So, the area of the rectange would be =
So, the area of the rectange would be =
A triangle is cut from the rectangle.
The height of the triangle is =
The base of the triangle is = 14
So area of the triangle would be =
area of the triangle would be =
area of the triangle would be =
So, the area of shaded region = area of rectange - area of triangle
the area of shaded region =
As per given in question, area of shaded region is 84, hence
equation
So, this is the equation for s : Answer
Hope it will help :)
