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.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

i think it is c hope that

b is the correct answer
