A bag contains some red, blue and yellow balls. 30% of the balls are blue and 40% are red. If there are 50 balls in the bag, how many are yellow?

Approximately, there is a distance of 25,6 foot between the base of the flagpole to the house.

Step-by-step explanation:

We are given the following in the question:

Height of pole = 20 foot

Angle between pole and ground = 85 degrees

Angle of elevation from the base of the house to the top of the pole = 55 degrees

Then, the third angle of the triangle can be found as:

Angle sum property of triangle: The sum of the three angles of a triangle is 180 degrees.

Thus, by the sin rule, we can write:

Approximately, there is a distance of 25,6 foot between the base of the flagpole to the house.
