A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94

So the pythagorean theorem is a^2 + b^2 = c^2. in this case it would be 12^2 + 8^2 = c^ 2

Explanation:
12^2 = 144
8^2= 64
64 + 144 = c^2
208 = c^2
in order to find c we need to square root both sides of the equation, you can plug that into the calculator.
c = about 14.4

2. Solve the system using substitution. (1 point)

AveGali [126]

Answer:

(8, 11 )

Step-by-step explanation:

Given the 2 equations

2x + 2y = 38 → (1)

y = x + 3 → (2)

Substitute y = x + 3 into (1)

2x + 2(x + 3) = 38 ← distribute and simplify left side

2x + 2x + 6 = 38

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Substitute x = 8 into (2) for corresponding value of y

y = 8 + 3 = 11

Solution is (8, 11 )
