Answer:
2:1
Step-by-step explanation:
The answer is A: 4/3=DE/9
4 is corresponding to line DE
3 is corresponding to 9
Answer: tan x
Step-by-step explanation: An angle determines if a side is opposite the angle, or adjacent the angle. Since p/a is something to do with the tangent, as it is not using the hypotenuse (the longest side.) Tangent is Opposite/Adjacent, while Sine is Opposite/Hypotenuse and Cosine is Adjacent/Hypotenuse. The only thing that makes sense is tangent.
So, that leaves us with either tan y or tan x. Well, with x, the angle that x points to (which is the opposite side) is p, and the adjacent is a, so p/a must be Tangent(x) since it is Opposite/Adjacent sides.
Only if it was r/p would it be tan y, since r becomes the opposite and p becomes the adjacent.
Answer: D) y = -1/4x + 6
Step-by-step explanation:
First turn the equation into slope-intercept form: y = 4x + 6
For a line to be perpendicular to another line, it's slope must be the opposite reciprocal of the other perpendicular line. Thus, the slope of the perpendicular line is -1/4. As the y-intercept of the line is (0,6), the lines must intersect as (0,6). Thus, the other line must also have a y-intercept of 6. Thus, the answer is D.
