Atriangle has sides of lengths 27, 79, and 84. is it a right triangle? explain.

a.) yes. 27^2 + 79^2 = 84^2
b.) yes. 27^2 + 79^2 ≠ 84^2
c.) no. 27^2 + 79^2 = 84^2
d.) no. 27^2 + 79^2 ≠ 84^2

No.

Step-by-step explanation:

For  a triangle to be a right angle triangle:

The two shorter side squared need to add up to longest side squared.

Let a and b are the shortest side and c be the longest then;

You can use Pythagoras theorem;

As per the statement:

A triangle has sides of lengths 27, 79, and 84

then;

Therefore, this violate the Pythagoras theorem;

therefore, this triangle is not a right angle triangle.

answer: c i think

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
