The length of the portion AB is 12tan45 if the A lamppost, CAB, bent at point A after a storm option first is correct.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
Length of BC = 12 feet
Angle ACB = 45 degrees
From the right angle triangle, ABC, apply tan ratio:
tan45 = AB/12
AB = 12tan45
Thus, the length of the portion AB is 12tan45 if the A lamppost, CAB, bent at point A after a storm option first is correct.
