Answer:

It is a right triangle.  

First, we sum the squares of 2 legs:

4.8^2 + 28.6^2 = 23.04 + 817.96 = 841

which equals the square of the longest side

29^2 = 841

When the sum of the squares of the 2 short sides of a triangle equals the square of the longest side, the triangle is a right triangle.

If √5 - x = 4,then x=<br>i need help on here how to solve it
Westkost [7]
Professor Dan Healy, one of my Engineering instructors back in prehistoric times,  had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it.  Here is Prof. Healy's method.

For a few moments, call the square root of 5 by the name "cow".

cow - x = 4 .    Solve this equation for 'x' :

Add 'x' to each side of the equation:  cow = 4 + x

Subtract 4 from each side:                cow - 4 = x

Now, we can put the real value back in place of 'cow' :  <u>√5 - 4 = x</u>

That right there is a perfect solution.  But If you absolutely need to
know the number, then grab your calculator:

√5 = 2.2361 (rounded)

x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
