Because of the given information angles 3 and 5 are considered alternate interior angles. Think alternate because they are on opposite sides and interior because they are on the inside.

These types of angles are congruent, therefore if m<5 = 58, then m<3 would also = 58.

If d is a transversal of parallel v and w, the angles 3 and 5 are alternate interior. Therefore, they are congruent. Angle 3 and 5 both measure 58.

Part A Prove that when x > 1, a triangle with side lengths a = x2 − 1, b = 2x, and c = x2 + 1 is a right triangle. Use the Py

Nataly [62]

Step-by-step explanation:

Given : A triangle with side lengths $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

To find : Prove that when x > 1, it is a right triangle. Use the Pythagorean theorem and the given side lengths to create an equation. Use the equation to show that this triangle follows the rule describing right triangles. Explain your steps ?

Solution :

For right triangle the Pythagorean theorem is to be satisfied.

i.e. $c^2=a^2+b^2$
