### Math Questions/Pythagorean Relationship Taylor

4. a) 8.4
b) 10.1
c) 7.4

9. What are all possible whole numbers that have a square root between 4 and 5?
17, 18, 19, 20, 21, 22, 23, 24
10. Kai uses an entire can of paint on a square backdrop for the school play. The label
on the can states that one can cover 27 squared metre of wall surface. Estimate the backdrop's side length, to one decimal place.

1. The Pythagorean relationship between the lengths of the sides of a right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.

2.
$a^2 + b^2 = c^2\!\,$
12+5=c
(12x12)+(5x5)=c
144+25=c^2
c^2=169cm^2
/c^2=/169cm^2
c^2=13cm

3. It is not a right triangle because a^2+b^2 does not equal c^2.
$a^2 + b^2 = c^2\!\,$
6^2+8^2=11^2
(6x6)+(8x8)=(11x11)
36+64=121
100X=X121
