Answer:
Trying to use a subject pronoun like he in a place of pool if the substituting sounds all right then use the subjective form who whom on the other hand is an object pronoun objective case therefore it should be used whenever it will do the job of direct object indirect object or object of preposition
Step-by-step explanation:
Answer:
107°
73°
Step-by-step explanation:
Let the two supplementary angles be x° and y°.
x + y = 180....(1)
Since, supplementary angles differ by 34.
Therefore,
x - y = 34....(2)
Adding equations (1) & (2)
x + y = 180
x - y = 34
_________
2x = 214
x = 214/2
x = 107°
Plug x = 107 in equation (1)
107 + y = 180
y = 180- 107
y = 73°
-13m = -377
m= -377/-13
m=29
the negatives cancel out. so just do 377/13 which equals 29
Explanation:
The line of reflection is the perpendicular bisector of the segment joining a point with its reflected image.
___
The segment joining a point with its reflection is as short as possible consistent with the requirement that the reflected point be the same distance from the line that the original is. That means it is perpendicular to the line of reflection. Since the distance from that line is the same on either side, the line of reflection bisects the joining segment.
R = speed in still water
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour
