Answer:
third side is 7 units
Explanation:
Hi there!
the Pythagorean theorem is given as a²+b²=c², where a and b are legs (the sides that make up the right angle) and c is the hypotenuse (side that is opposite to the right angle, or in this case, the third side)
we are given the lengths of the 2 legs, and we need to find the hypotenuse
a=6
b=√13
c=unknown value
square the values of a and b, add them together, and set that to equal c squared
or in other words:
6²+(√13)²=c²
36+13=c²
(because 6*6=36; √13*√13=13)
49=c²
√49=√c²
7=c
therefore the hypotenuse is 7 units
Hope this helps!
