Does a=2.1 b=7.2 c=7.5 form a right triangle

Anna007 [38]

Answer:

Yes

Step-by-step explanation:

If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle

longest side = 7.5

7.5² = 56.25

2.1² + 7.2² = 4.41 + 51.84 = 56.25

Thus the 3 values form a right triangle.

The percent error is 6.25%

Step-by-step explanation:

Percent error is given by:

$Percent\ Error=\frac{|Experimental\ Value -\ Accepted\ value|}{Accepted\ value}*100$

Here,

Accepted value = 80.0°C

Experimental Value = 75.0°C

Putting the values in the formula

$Percent\ Error=\frac{|80.0 -75.0}{80.0}*100\\=\frac{|5.0|}{80.0}*100\\=\frac{5.0}{80.0}*100\\=0.0625*100\\=6.25\%$

Hence,

The percent error is 6.25%
