How to find the length of a square inside a circle?

Follow these steps to find the length

First check whether any radius of the circle is given or not.

We know that diameter = 2× radius.

The diameter is 2 r . The diameter is also the diagonal of the given square.

So 2 r is the diagonal of the square.

Let the side of square be s.

The diagonal is √2s

Now √2 s = 2 r

Square both sides to get : 2 s²= 4 r²

⇒s²=2r²

If r is given we can find s which is the required length of the square.

Step-by-step explanation:

i believe a. 12x≥120 is the answer

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
