Question

A car ramp is 28 m long and makes an angle of 15° with the horizontal. A scale drawing is to
be made of the ramp using a scale of 1 cm to 5m.

a How long will the ramp be on the drawing?

b What angle will the ramp make with the horizontal on the drawing?

Answer 1

Answer:

a)28/5=>5.6cm

b)15° As the angle doesn't change

Answer 2

Answer:

a) 5.6 cm

b) 15°

Step-by-step explanation:

a) Divide the actual length by the scale factor.

        28/5 = 5.6

So the answer is 5.6 cm.

b) Changing the size of the ramp will not affect the angle in any way, so the drawing will have the same angle as the actual ramp.
