Answer: 51 uinits
The three numbers are x , x + 21 and x + 27.
The greatest of the 3 numbers is x + 27, so x + 27 has to be the hypotenuse.
----------------------------------------------
Pythagoras Theorem
----------------------------------------------
a² + b² = c²
x² + (x+21)² = (x+27)²
x² + x² + 42x + 441 = x² + 54x + 729
x² - 12x -288 = 0
(x - 24)(x + 12) = 0
x = 24 or x = -12 (rejected, length cannot be negative)
----------------------------------------------
Find hypotenuse
----------------------------------------------
Hypotenuse = x + 27 = 24 + 27 = 51 units

Answer: 51 units

a)
there are total 3 diffrent shades
because
(i) A = C = 1/2 so one shade
(ii) B=D =F = 2/3 so one shade
(iii) E = 5/8 one shade
so total 3 different shade
b )
(i) y = 1/2 b
(ii) y = (2/3) b
(iii) y = 5/8 b
All you have to do is replace the number in the function with “y”
For example:
p(0):
=2-y+1
=2-0+1
=1
*remember BEDMAS*
Im sure the rest is self-explanatory
Hope that made sense:)
