B. 18.5m
Step-by-step explanation:
This involves the use of trigonometric ratios to find the lengths of missing sides. In this case, we are using the tangent ratio because we are given the adjacent leg to the angle and need to find the length of the side that is opposite of the angle. Tangent is the ratio of the opposite side to the adjacent side of the triangle.
x=height of flagpole
tan(40°)=x/22
tan(40°)*22=x/22*22
tan(40°)*22=x
x = 18.46
The height of the flagpole is 18.5m tall. Therefore b. 18.5m, is the correct answer.

Step-by-step explanation:
The given data shows that only 1 row was in use. We also know that Mr. Torres is an adult. So for the ease, lets use A for Adult and S for student.
The seating must fulfill the requirements that 4 students must be between adults such that it would be "A-S-S-S-S-A"
On a row of 11 seats, this should be the searing arrangements.
A-S-S-S-S-A-S-S-S-S-A ( for 1 row).
Mr. Torres could be any A .
