Calculating the height of the barn.
We can now calculate "H" by creating a scale drawing.
In our scale drawing 1 cm will represent 1 meter.
With a ruler draw a 10 cm baseline.
Draw a line at 90 degrees at one end and 38 degrees at the other.
These lines intersect at the peak of the barn.
Measure "H" in cm, this number represents "H" in meters.
We have calculated that H=7.8 meters, OS the offset was 1.52 meters.
Adding 7.80m + 1.52m, we get the height of the barn, 9.32 meters.
