Given:
Planes X and Y are perpendicular to each other
Points A, E, F, and G are points only in plane X
Points R and S are points in both planes X and Y
Lines EA and FG are parallel
The lines which could be perpendicular to RS are EA and FG.
Jy has hiked 17km
He is 2km short of being half of the way done with hicking
Let the total distance he hiked be xkm
Then 1/2x = 17 + 2km
1/2x = 19km
x = 19 × 2 = 38km
The total distance he covered was 38km.
Answer:
find the classmark of each interval
- forexample
- (140+150)/2
- (150+160)/2
do the same up to (190+200)/2
then
draw a graph by using frequently (number of weeks) on y-axis against classmark on x-axis
Answer:

Step-by-step explanation:
Two triangles are congruent by AAS postulate if two adjacent corresponding angles are congruent and the next adjacent sides to any of the angles is are also congruent. The adjacent sides should not be in between the two congruent angles.
From the triangles RQS and UTV

The adjacent side to
is RQ and for
is UT.
Similarly, the adjacent side to
is QS and for
is TV.
So, the possible sides that could be congruent by AAS postulate are:
or 
So, the correct option is
