Step-by-step explanation:
Answer:
third side = 9
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let the third side be x, then
x² + 40² = 41², that is
x² + 1600 = 1681 ( subtract 1600 from both sides )
x² = 81 ( take the square root of both sides )
x = 
= 9
The third side is 9
I think it’s b but I’m not sure
It is an isosceles triangle because it has two equal sides and a hypotenuse.
We have given that
A triangle has 2 sides that equal 5 inches. The other side equals 4 inches.
We have to determine the type of the triangle
<h3>Which triangle has two sides that are equal?</h3>
An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.
Therefore,It is an isosceles triangle because it has two equal sides and a hypotenuse.
