a) Approximately 40° for depression and 5° for elevation; b) it relates to the height of the observer; c) none. Step-by-step explanation: (a) Angles of depression and elevation: The angle of depression is roughly 40°, while the angle of elevation is around 5°. (b) The angles depend on the observer's height. A taller individual will have a smaller angle of elevation paired with a larger angle of depression. (c) None of the angles can reach or exceed 99°, since they are components of a right triangle. If one angle is a right angle, both of the others must be lesser than 90°.

“The perimeter P of a triangle is equal to the sum of the lengths of sides a,b, and c”
AnnZ [9099]

Answer:

1. Calculate the sum of "a", "b" and "c".

2. The perimeter equation is: P=a+b+c

Step-by-step explanation:

In this case, P denotes the triangle's perimeter while a, b, and c are the triangle's sides.

The definition states that the sum results from an addition operation. Thus, the statement "The perimeter P of a triangle equals the total of sides a, b, and c" means that the perimeter is determined by aggregating the lengths of the triangle's sides.

Consequently, you can express this in the following equation:

P=a+b+c

Inessa [9000]
P(X \ Y) = P(X ∩ Y)/P(Y)
P(X ∩ Y) = 80/1000 = 0.08
P(Y) = 580/1000 = 0.58

P(X \ Y) = 0.08/0.58 = 8/58 = 4/29

Response:1 and 2

Step-by-step Explanation:

Provided data

Volume required V=220\ in.^3

For the initial cylinder

r=3\ in.

h=4\ in.

V=\pi r^2h

V_1=\pi (3)^2(4)

V_1=113.11\ in^3

For the second cylinder

r=4\ in.

h=4\ in.

V=\pi r^2h

V_2=\pi (4)^2(4)

V_2=201.08\ in^3

For the third cylinder

r=9\ in.

h=9\ in.

V=\pi r^2h

V_3=\pi (9)^2(9)

V_3=2290.51\ in^3

For the fourth cylinder

r=4\ in.

h=9\ in.

V=\pi r^2h

V_4=\pi (4)^2(9)

V_4=452.448\ in^3

Thus, cylinders 1 and 2 meet the requirement as they remain under 220\ in.^3
