Hi Lalaloves;

I think you need to improve the diagram I can not see it at all.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Find the missing length of the triangle.

Hi;

I will help as soon as I see the drawing.

Do you have a right triangle there with sides of 4 and 10 and the hypotenuse is x?

Please stay on the forum so that I can ask you questions because your diagram is still unreadable.

Or is it 2 similar triangles? One with sides 10,10 and 4 and the other one with sides 2 and x?

Re: Find the missing length of the triangle.

Hi;

If the triangles are similar then the angles are the same and the sides are in proportion. So if the base equals 4 on the large one and 2 on the small one then the small one's base is half as large. So the remaining sides are half as large as well.

x = 10 / 2

x = 5

Hope I am interpreting your question correctly and welcome to the forum.
