Answer:
y=40x
Step-by-step explanation:
A key word to remember when doing this type of math is "SOHCAHTOA".
Sine =
Opposite over
Hypotenuse
Cosine =
Adjacent over
Hypotenuse
Tangent =
Opposite over
Adjacent
Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.
And the Hypotenuse would be simplified to 5.
So, the answer is 4 / 5!
Step-by-step explanation:
multiplying eq 1 by 4and eq 2 by 3 ,we get
-12x+4y=28
-12x+12y=-36
solving eq 1and 2
4y-12y=64
-8y=64
y=-8
x=-5
Use the trigonometric function
