Answer:
The correct answer is
D) 66.35
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.
So in shorthand notation:
sin = o/h cos = a/h tan = o/a

Answer: 4
Step-by-step explanation:
Set them equal to each other since they're both equal to y
3x-5=.5x +5
add 5 to both sides
3x=.5x+10
subtract .5x from both sides
2.5x=10
divide both sides by 2.5
x= 4
Divide 45 and 9 it was give you -5
