Answer:
First option: Multiply the first equation by-1 and add the equations together.
Third option: Multiply the second equation by -1 and add the equations together.
Step-by-step explanation:
The method to solve a system of equations using addition is known as Elimination Method.
The idea is to get an equation with one variable, solve for that variable to find its value and the substitute this into any original equation to find the value of the other variable.
In this case, multiplying the first equation by -1, you get:
Multiplying the second equation by -1, you get:
I think you guys are using a^2 + b^2 = c^2
the equation would be
x^2 + 2x^2 = 6^2
The answer is D!!! hope this helps

<u>Answer</u>
A) 40°
<u>Explanation</u>
Assuming that the angles are measured from the center, we can use the properties of a circle to find <CAE.
Angles subtended by at the center by the same arc double the angle at the circumference.
