Here is a scale drawing.
The Ferris wheel has a height of 134 m
Work out the height of the building.
3.25 cm
0.65 cm
Ferris wheel
Building

The units of actual heights are measured  in meters, thus we can say that the actual height of the building is 670 m

Step-by-step explanation:

Step 1

In the question it has been given that

Actual height of Ferris wheel = 134 m.

Height of Ferris wheel using the scale = 0.65 cm

Height of building after using the scale - 3.25 cm

Step 2

Let  us assume that the actual height of building be x meters.

Since, we are making use of the  same scale, the ratio of actual heights to that of scaled down heights is the same for both objects.

It means that ,

Ratio of Actual Height to scale height of Ferris Wheel = Ratio of Actual Height to scale height of the building

Step 3

Substituting the values, we get:

Step 4

Thus we can say that  the actual height of the building is 670 m

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
