Answer:
x =3.375
Step-by-step explanation:
We can use proportions to solve this problem. Put the smaller triangle side length over the larger triangle side length.
6+x 12
---------- = -----------
25 32
(6+x) *32 = 12*25
Distribute
192 +32x = 300
Subtract 192 from each side
192-192 +32x = 300-192
32x =108
Divide by 32
32x/32 = 108/32
x =3.375
First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
