Answer:
y = (5/2)x + 6
Step-by-step explanation:
The given line has a slope (coefficient of x) of -2/5. The perpendicular line will have a slope that is the negative reciprocal of this:
-1/(-2/5) = 5/2
Since you are given a point you want the line to go through, the point-slope form of the equation of the line is useful. That form for slope m and point (h, k) is ...
y = m(x -h) +k
For your slope m=5/2 and point (h, k) = (-2, 1), the equation of the line is ...
y = 5/2(x +2) +1
y = 5/2x +6 . . . . . eliminate parentheses
Answer:
<em>Yes.</em>

Answer:
Case I, Case II
Step-by-step explanation:
For cases III and IV, you need the Law of Cosines.
The Law of Sines can be used when you have at least one side and the angle opposite. If you know two angles of a triangle, you know all three, so the given angles don't necessarily have to be opposite the given side if two angles are known.
The Laws of Sines can be applied to solve Case I and Case II.
False because the obtuse angle is to large to complement the right angle to diffrent angles can not be both of their compliments
