Width =p/2-h P=30 H=10 W=30÷2-10=5cm
w=5cm l Length 10 cm P Perimeter 30 cm Using the formula P=2(l+w) Solving forw w=P 2﹣l=30 2﹣10=5cm
In a regular hexagon, all interior angles are equal. The sum of the interior angles of a hexagon is:
(6 - 2) × 180° = 720°
Since there are 6 equal angles:
Each angle = 720° / 6
Each angle = 120°
The formula for area is:
Area = Length * Width
96 = L * 3
L = 96 / 3
L = 32
The surface area of a sphere is given by the formula: 4πr².
Substituting r = 7 cm, we get 4 × 3.1416 × (7)² = 616 cm².
The number of diagonals in a polygon can be calculated using the formula:
n(n-3)/2
where n is the number of sides.
For a 12-sided polygon (dodecagon):
n = 12
Number of diagonals = 12(12-3)/2
= 12(9)/2
= 108/2
= 54
Vertical angles that are opposite to each other are also Equal
Vertical angles are equal, so set up an equation:
80° = 4x
Divide both sides by 4:
x = 80° / 4
x = 20°
An angle is a figure formed by two rays, called the sides of the angle,
Two lines that make an angle are called rays
In plane geometry, an angle is a figure formed by two rays,
