4. To determine if a triangle is a right triangle, given that you know the length of its sides, you have to check if its lengths follow the Pythagorean theorem.
This theorem states that the square of the hypothenuse (c) is equal to the sum of the squares of the legs of the triangle (a and b), following the expression:

The triangle is:
We have to check that a²+ b² is equal to c².
The square of the hypothenuse is:

The sum of the squares of the legs of the triangle is:

As you can see, the sum of the squares of the legs of the triangle is 100, which is the same as the square of the hypothenuse. The triangle follows the Pythagorean theorem and can be considered a right triangle.
From the term line the term angle can be defined because when two lines intersect at a point an angle is formed. An angle is defined as a figure which is formed when two lines intersect each other at a point. ... Therefore, the undefined term which is used to define the term an angle is line.
Answer: 2x and x2 are the same
Step-by-step explanation:
Answer:34.93
Step-by-step explanation:
Using a^2+b^2=c^2we can substitute a and b in which is 34^2+8^2=c^21156+64=c^21220 = c^2Now we need to square both sides√1220 = √c^234.9284983931 ----> 34.9334.93 = cc = 34.93
