If you plug in the x and y, you get
7(1)(3)
7 x 1 x 3 = 21, so the answer is 21
You would round down to 25,000
Let first consider the equations one by one and will be solving one by one ;
Multiplying both sides by y will lead ;
Now, consider the second equation which is ;
Multiplying both sides by x will yield
As LHS of both equations (i) and (ii) are same, so equating both will yield;
Multiplying both sides by 4 will yield
Dividing both sides by y will yield :
<em>Hence, the required answer is 16</em>
To reflect over the x axis you just multiply the y value by -1 . So your answer is (5,3)
So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!
