A vertical pole 6 feet long casts a shadow 55 inches long. Find the angle of elevation of the sun. Draw a diagram and find the a
ivolga24 [154]

A vertical pole(AB) 6 feet long casts a shadow(CB) 55 inches long as shown in the attached image. Since the angle of elevation of sun is \angle C. We hav to find the value of \angle C.

Firstly, we will change the dimensions of pole(in feet) to the dimension of shadow( in inches) . So, that the dimensions of pole and shadow are same.

Since, 1 feet = 12 inches.

6 feet = 6 \times 12 = 72 inches.

Now, let us consider the triangle ABC in the attached image,

We have to find \angle C

tan\Theta =\frac{Perpendicular}{base}

\tan C= \frac{AB}{BC}= \frac{72}{55}

= 1.309

= 52.6^{\circ} = 53^{\circ}

How to estimate 55 percent of 64?
serious [3.7K]

Answer: 35.2

Step-by-step explanation: To estimate 55 percent of 64, you could round the 55 to 50 percent, and just find half of 64, which is 32. After this, because you only have 5 percent left over, you can take the number you got from 50% of 64 and move the decimal over one place to make it 3.2. Just add that number to 32 and you’ll get your answer.
