The correct answer is A. 109 degrees.
Explanation:
Because the angles are supplementary, their sum is 180 degrees.
We know that one of them is 71 degrees, so we substract that from 180, therefore the other angle is 109 degrees.
Answer:
Step-by-step explanation:
<u>Given</u>
<u />
<u>Step 1: Combine Like Terms on LHS</u>
<u />
<u>Step 2: Subtract 11 on both sides</u>
<u />
<u>Step 3: Divide both sides by -4 to isolate the x-variable</u>

<u>Final Answer</u>
<u />
Answer: 18
Step-by-step explanation:
Using the Triangular Prism formula,
V=A (sub)B(sub) h
Solving for A (sub)B(sub)
A (sub)B(sub) = V/h = 162/9 = 18

Answer:</h3>
(x, y) = (6, -6)
<h3>
Step-by-step explanation:</h3>
Divide the first equation by 2 to get equal and opposite coefficients for x.
... -2x -y = -6
Add this to the second equation to eliminate x.
... (2x +4y) +(-2x -y) = (-12) +(-6)
... 3y = -18 . . . . . . . . simplify
... y = -6 . . . . . . . . . . divide by 3
Substitute this vaue into any of the equations to find x. We choose to use the reduced first equation above.
... -2x -(-6) = -6
... -2x = -12 . . . . subtract 6
... x = 6 . . . . . . . divide by -2
The solution to the system is (x, y) = (6, -6).
