Carlos calculated the missing side length of one of these triangles using the pythagorean theorem. which triangle is it?

For this case, we have that by definition, the Pythagorean theorem can only be applied to rectangular triangles.

The Pythagorean theorem states that:

Where:

a, b: are the legs

c: it is the hypotenuse.

In this case the rectangle triangle is in option A.

Option A

The first triangle

Step-by-step explanation:

The Pythagoras theorem is used to calculate the side length of the right angle triangle.

The theorem says that the sum of the square of the two shorter legs of a right angle is equal to the square of the hypotenuse.

From the given triangles, the only one which is a right angle triangle is the one with side lengths 2 and 3 .

The first triangle from left to right.

step-by-step explanation:

it's 15

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
