X = 180 - 90 - 12 = 78° (Sum of all angles in a triangle is 180)
Answer: x = 78°
Using the slope concept, it is found that the angle of elevation to the top of the bridges is of 57.7º.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>.
It's also the tangent of the angle of depression.
In this problem:
- The horizontal change is of 60 m.
- The vertical change is of 100 - 5 = 95 m.
Hence:



The angle of elevation to the top of the bridges is of 57.7º.

We are given
The current exchange rate is 2 guilders for every 3 florins
so,
2 guilders = 3 florins
now, we can find for 1 guilders
so, we get

now, we can multiply both sides by 17

now, we can simplify it

so, option-A........Answer
