I'm not sure on what exactly your equation is supposed to be...so I rewrote it
Use Pythagorean theory
C^2 = a^+ b^2
In this case you have c and a
B^2= c^2-a^2
B^2 = 12^2-5^2
B^2= 144-25
B^2 = 119
Square root both sides
X= 10.90871
Answer:
$22.5
Step-by-step explanation:
Jim gets 9*2.5= $22.5
Y = -6x + 3
In y = mx + b form, the slope will be in ur m position...
y = mx + b
y = -6x + 3
so ur slope (the number in the m position) is -6
If it has 3 sides then it's a triangle.
Using the formula
where

and a=5 b=5 c=8
∴
