You need the cubic root of 27, which is 3. This means each edge is 3cm
Answer:
X = 50
Step-by-step explanation:
(5x - 100) + (x - 20) = 180 (sum of angle on a straight line is = 180)
5x + x -100 -120 = 180
6x - 120 = 180
6x = 180 + 120
6x = 300
x = 300/6
x = 50
For y
3y + y + 140 = 180
4y = 180 -140
4y = 40
y = 40/4
y = 10
Here's the solution,
there's a rectangle with sides 4x and 2x
So, area of rectangle :
=》4x × 2x
=》8x²
now, let's divide the kite into two equal triangles with base = 4x
and height = x
area of each triangle :
=》

=》

=》

=》

now, area of each triangle = 2x²
and there are two triangles so,
Area of the kite will be :
=》2 × 2x²
=》4x²
Area of shaded region =
=》Area of rectangle - Area of kite
=》8x² - 4x² = 4x²
hence, correct option is B.
