A triangle has two sides of length 15 cm and 17 cm. Select all the values of its third side that would make it a right triangle
Natali [406]

Answer:

\sqrt{514} cm, 8cm, are both options

Step-by-step explanation:

For a right triangle one can find the length of the longest side by using the Pythagorean theorem. So there are two options I can think of that if the triangle is a right triangle will work. First remember what the Pythagorean theorem is : side a^2+side b^2=hypotenuse^2

The hypotenuse is the longest side of a right triangle. So if the sides that are 15 and 17 cm are not the longest sides then the formula would be:

15^{2} +17^2=c^2\\15^2+17^2=\sqrt{514}cm

But if 17cm is the longest side then:

a^2+15^2=17^2\\8^2+15^2=17^2\\a=8cm

Hope this helps!

Answer:

Step-by-step explanation:

it's 2ab + c^ 2

why?, well, we can change the position of the 2 triangle in each corners into this (in the picture below) :

you can see that a^2 + b^2 = c^2

then there are 2 ab from 4 triangles we add that create 2 rectangle then we multiply each rectangles by its sides

so , c^ 2+ 2ab is the answer

I

hope this is helpul!
