Landon welded three pieces of metal together to form a triangle with side lengths that measure 8 inches, 9 inches and 17 inches.

Ray Of Light [21]

Answer:

<h3>No, it is not a right triangle</h3>

Step-by-step explanation:

In order to know whether the triangle is a right angle, we need to show that the square of the longest side is equal to the sum of the square of the other two sides

Longest side = 17in

other two sides = 8in and 9in

Check:

17² = 289

Sum of the square of other two sides

= 8² +9²

= 64 + 81

= 145

Since 17² ≠ 8² +9², hence the triangle that Landon created is not a right triangle

How to change 3 7/8 into an improper fraction

VladimirAG [237]

3 7/8

So we can use this $a \frac{b}{c} = \frac{(a \times c) + b}{c}$

So we get

$3 \frac{7}{8} = \frac{(3 \times 8) + 7}{8}$

= $\frac{24+7}{8} = \frac{31}{8}$
