Which equation finds the length of side c of this right triangle?
A.)c=√a2-b2
B.)c=√a2+b2
C.)c=√a2+√b2
D.)c=a2+b2
I think it is D.)
The correct answer is B.) c=√a^2+b^2. This equation is known as the Pythagorean theorem and is used to find the length of the hypotenuse (side c) of a right triangle.
The equation that finds the length of side c of a right triangle is the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, this can be expressed as:
c^2 = a^2 + b^2
To find the length of side c, you would take the square root of both sides of the equation:
c = sqrt(a^2 + b^2)
So the correct answer is B) c = √(a^2 + b^2).
