Use the sine rule.
For any triangle: sin(a) / A = sin(b) / B = sin(c) /C
Where A is the side opposed to angle a, B is the side opposed to angle b, and C is the side opposed to angle c.
Here, sin(B) / AC = sin(A) / BC = sin (C) / AB
<span> BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°
sin(37) / 8.75 = sin(A) / 12.35 => sin (A) = 12.35 * sin(37) / 8.75
sin(A) = 0.845 = A = arctan(0.845) = 58.15°
And A + B + C = 180° => C = 180 - A - B = 180 - 58.15 - 37 = 84.85
Answer:
measure of angle A = 58.15°
measure of angle C = 84.85 °

You would need to have the information of how it translated, wether it was left or right, or up or down. you would also want the information of how far it translated.
The good option to multiply the top equation by is <u>-4</u>
<h3>
REASON :-</h3>
This is because, when we solve the equations, in the left side of first equation :-
☆ -2 can be multiplied by <em>-4</em><em> </em>to get the value 8 on the left side of second equation.
☆ This can help in easier elimination in the given set of equations.
■ The process is to be done as per the given below way :
Now the 8x on both equations can be cut.
