12. From the top A of a building 125m above a street, the angle of elevation of the top B of a second building on the opposite side is 18'36'and the angle of depression of the base of the second building
from A is 39° 48
(a) Calculate the width of the street​

answer: i can’t tell you that

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

6 × 4.3 = 25.8

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
