Here is a scale drawing of two buildings. The difference between the actual heights of the buildings is 20 metres. Work out the height of the taller building. Note: the height of the small building on the drawing is 4.5 cm, and the height of the tall building is 6 cm.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
