Try the suggested solution with short explanation; red line means the curve between the first point (on the midline) and the closest maximum; the - - - - line means the curve between the first point (on the midline) and the closest minimum.

The triangles given below in the diagram are similar by; D: The SSS Similarity theorem.

<h3>How to interpret similar triangles?</h3>

From triangle similarity theorems, we know that;

If a segment is parallel to one side of a triangle and intersects the other two sides, then the triangle formed is similar to the original and the segment that divides the two sides it intersects is proportional.

Now, from the given diagram, we see the ratio of corresponding sides are congruent as;

45/30 = 54/36 = 36/24 = 1.5

Thus, the triangles are similar by SSS similarity theorem

What is the approximate surface area of a cylinder with a radius of 3 inches and a height of 10 inches?

xxMikexx [17]

245in^2

Curved surface = 2pi x r x h = 2 x 3.1 x 3 x 10 = 186
2 ends = 2 x (Pi x r x r) = 2 x 3.1 x 3 x 3 = 55.8
Total area = 186 + 55.8 = 242in^2 approximately

The measures of both

m_a_m_a [10]

Answer:

m<EAD=29°

m<CAB=119°

Solution,

< CAE+<EAD+90°=180°( angles on a straight line)

61+<EAD+90°=180°

<EAD=180-(90+61)

 =180-151

 =29°

<CAB+<FAB=180°( Linear pair)

<CAB+61°=180°

<CAB=180°-61°

<CAB=119°

hope this helps ..

Good luck on your assignment..

Electrical poles that carry elecrtical wire seem to get smaller the farther away they are. Find the apparent height of each pole

lisabon 2012 [21]

Answer:

The answer to the question is;

Then the apparent height of each pole if the tallest pole is 50 feet tall and there is 100 feet between each pole is $\frac{50*x}{(x + 100*n)}$ .

Step-by-step explanation:

To answer the question we have

Let the location of the closest pole = x

Let the height of the closest pole = h feet

Also let the actual height of the pole at location 100×n feet away be 50 feet

Where n = 1, 2, 3, ...∞

Then we have by taking tangent of the similar triangles so formed by the poles

Then h/x = 50/(x +100·n)

Therefore h = 50 × x/(x +100·n) = 50·x ÷(x + 100·n) = $50 \frac{x}{(x + 100n)}$ feet

The apparent height of each pole if the tallest pole is 50 feet tall and there is 100 feet between each pole is 50·x /(x+100·n) where n is the number of 100 feet further away the pole is e.g when n = 1 we have

h = 50·x /(x+100·1) = 50·x /(x+100)
