Answer:
cos θ= 24/25
Step-by-step explanation:
Draw a triangle to help.
We know the hypotenuse is 25 since sin is opposite/hypotenuse.
We know the side opposite to theater is 7 and the side adjacent to theater is 24, since tan is opposite/adjacent.
Answer:
x - 2y = 2
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and A, B are integers )
given y = x - 1
multiply through by 2 to eliminate the fraction
2y = x - 2 ( subtract 2y from both sides )
0 = x - 2y - 2 ( add 2 to both sides )
x - 2y = 2 ← in standard form
