Okay, here we have this:
Considering the provided angle, we are going to calculate the requested trigonometric functions, so we obtain the following:
So the first thing we will do is calculate the length of the hypotenuse, that is, the distance between the given point and the origin, then we have:

Now we proceed to find the value of each ratio:





Answer:
42.9m
Step-by-step explanation:
The topic is on similar triangle
you are comparing triangle MNP with triangle MAB
side AB is similar to NP
side MA is similar to MN
side MB is similar to MP
now MA = MN - AN
= 67.2 - 32
= 35.2m
MA/MN = MB/MP
35.2/67.2 = x/81.9
cross multiply and solve
x = 42.9m
