Answer:
The area of the ΔAOB is .
Step-by-step explanation:
As given the figure
OA = OB = 6 unit
(Radius of the circle.)
In ΔAOB
As the two sides of a triangle thus there opposite angles are also equal .
∠A = ∠B
Let us assume that ∠A = ∠B = x°
∠A + ∠O + ∠B = 180°
(By using the angle sum property of a triangle.)
∠O = 60°
x° + 60° + x° = 180°
2x = 180 - 60
2x = 120
x = 60
∠A = ∠B = 60°
Thus
∠A = ∠B = ∠O = 60°
As all the angles of the ΔAOB are 60° thus ΔAOB is a equilateral triangle .
Also all the sides of the ΔAOB are also equal i.e AB = OA = OB = 6 unit .
Formula
Where a is the side of the equilateral triangle .
a = 6 unit
Put in the above formula
6² = 36
Therefore the area of the ΔAOB is .
It is an application of Pythagorean Theorem
And it is clear that the lower angle is 30 and the apex angle is 60 (this is how always normal TVs look like) ... refer to the image I attached
So, to calculate the width and the length:
You can after that round the length to be 22.517 in
Hope you got the idea
