Answer:
14x-11y
Step-by-step explanation:
6x-2y-5=5-9y+8x
eliminate opposites
6x-2y-9y+8x
collect like terms
14x-11y
Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees
Hope this helps! :)
Answer: x = -3
Step-by-step explanation:
i simply divided by -7, in order to get x by itself.
