A right triangle is a triangle with one angle measuring 90°. In a right triangle, the lengths of the sides are related by the Pythagorean Theorem, c2 = a2 + b2 where c is the length of the hypotenuse (the side opposite the 90° angle). Find the length of the hypotenuse when the other two sides’ measurements are 3 feet and 4 feet.
NOTE: c2 = a2 + b2 - the number 2s are Superscript (I didn't know how to type that for this question)....

This is very basic geometry.
The answer is 5
since
a=3 and b=4
= c^2 =a^2+b^2
= c= *square root of* a^2 + b^2
= c= *square root of* 3^2 + 4^2
= c= *square root of* 9 +16
= c= *square root of* 25
= c= 5

9 + 16 = 25 25 is c^2 so c = 5 use this to solve the other problem , 35^2 + 65^2 = c^2 hope this helped.

IT'S simple...
'c' is always the side opp. to the angle C.
'b' is opp. to.B.
'a'.is opp. to A.
so take a =3 feet, b= 4 feet.
using, c2 = a2+b2
c2 = 9+16
c2 = 25
so, c = 5.

c^2=a^2+b^2
c^2=3^2+4^2
c^2=25
c=5
25=9+16
