A triangle has one leg measuring 10 inches and the hypotenuse measuring 20 inches. the other leg measures 10\sqrt[]{3} 10 3 inch
stiv31 [10]
From the description given for the triangle above, I think the type of triangle that is represented would be a right triangle. This type of triangle contains a right angle and two acute angles. In order to say or prove that it is a right triangle, it should be able to satisfy the Pythagorean Theorem which relates the sides of the triangle. It is expressed as follows:

c^2 = a^2 + b^2

 where c is the hypotenuse or the longest side and a, b are the two shorter sides.

To prove that the triangle is indeed a right triangle, we use the equation above.

c^2 = a^2 + b^2
c^2 = 20^2 = 10^2 + (10sqrt(3))^2
400 = 100 + (100(3))
400 = 400

Which of the following is most likely the next step in the series?
kupik [55]

The circles in the figures form a series

The next step in the series is (B)

<h3>How to determine the next step?</h3>

From the figure, we have the following highlights

  • The first circle has 2 segments
  • The second circle has 4 segments
  • The third circle has 5 segments

Using the above pattern, the next circle must have 6 segments

Hence, the next step in the series is (B)
