Answer:
(c-a,b)
Step-by-step explanation:
Bottom of shape is equal to 4a, or c.
R is to be located at (3a, b)
c-a=3a, ∴r: (c-a,b)
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees

We are given with
walking speed = 5 km/hr
bus speed = 60 km/hr
total distance = 35 km
total time = 5 hr
To solve this, we use the equations
x + y = 5
5x + 60y = 35
The solution is
x = 4.82 hr
y = 0.18 hr<span />
