Answer:
3
Step-by-step explanation:
Find 'c' first by using the Altitutude Rule:
4/c = c/9
cross-multiply to get:
c =
or 6
Now you can find 'a' by using the Pythagorean Theorem:
4² + 6² = a²
a = 
Now you can find 'b' by using the Pythagorean Theorem:
(
)² + b² = (9+4)²
52 + b² = 169
b² = 
b =
= 


b = 3

There are fours ways to solve polynomial equations..........
Polynomial Equation Degree Example
Linear Equations 1 -3x + 1 = 4x + 5
Quadratic Equations 2 x2 – 6x + 9 = 0
Cubic Equations 3 x3 – 2x2 + 3x = -5
Quartic Equations 4 x4 – 2x2 = -4
It's really not that hard.....
