Aright triangle has legs with lengths 20 cm and 21 cm.
what is the length of the hypotenuse?
_cm

 Ue use the theorem:

 The equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": 

where c represents the length of the hypotenuse  (the side opposite the right angle) and a and b the lengths of the triangle's other two sides.

;

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
