Answer:
i think its 7n/4
Step-by-step explanation:
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.

Answer:
4.9361
Step-by-step explanation:
Rieman sum = ∫∫ΔA
ΔA = ΔxΔy
Δx = = = pi/2 = Δy
ΔA = pi/2 * pi/2 =
Evaluating at the four corners
=
= 2
∫∫ΔA = 2 * = = 4.9361
Obtuse, acute, and right.
Answer:
1.99
Example:
Increase 10 by 99%. 99% of 10 is 9.9 so increased value would be 10 + 9.9 = 19.9
10 x 1.99 = 19.9 ... same answer
