Requiem needs to know if the triangle shown is a right triangle. Which equation could he use to help ?

B

Step-by-step explanation:

There isn't enough information because you never gave me the picture, but i think the triangle has sides 5 6 and 7 and is not a right triangle. You must apply the pythagorean thereom.

Pythagoras theorem: hypotenuse² = opposite² + adjacent²

Step-by-step explanation:

To know if a triangle is a right angle, we need to have the length of each sides of the triangle. Then we would apply Pythagoras theorem to determine if it is truly a right angled triangle.

Pythagoras theorem is a theorem in the form of an equation which shows the relationship between the sides of a right angled triangle.

let the sides of the right angled triangle be:

opposite =a, adjacent = b and hypotenuse = c

Using Pythagoras theorem

hypotenuse² = opposite² + adjacent²

c² = a² + b²

If the left hand side of the equation = the right hand side of the equation, it is a right angled triangle.

72 is the answer to this problem

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
