Slopes of perpendicular segments are always negative reciprocal of each other. Or, we can say product of slopes of perpendicular segments is always -1.
Given the slope of PQ is 5/2.
So the slope of its perpendicular segment should be -2/5.
Finding slopes of given options:-




From above calculations, it is clearly visible that slopes of RS and VW are negative reciprocal of slope of PQ.
So, correct answers are RS and VW.

Answer:
<h2>x = 1</h2>
Step-by-step explanation:
Look a t the picture.
The triangles on the picture are similar.
Therefore the sides are in proportion:
<em>cross multiply</em>

<em>divide both sides by 40</em>

4.7 x 10 : 3.1 x 10
= 47 : 31
Remember: a^2 + b^2 = c^2

64 + 49 = 113
√113 = 
2
100 - 25 = 75
square root of 75 = 5
