Answer:  The flagpole is about 22.3 feet tall.

This is roughly the size of a two story building, assuming each floor is 10 feet or so.

Since this height is under 25 ft, this flagpole is in compliance with the regulation.

=====================================================

Work Shown:

The horizontal leg of the triangle is 36 ft. This is the adjacent leg to the reference angle 25 degrees.

The vertical leg of the triangle is x-5.5, and this leg is the opposite side to the reference angle 25 degrees.

Use the tangent rule to connect the opposite and adjacent sides.

Solve for x.

tan(angle) = opposite/adjacent

tan(25) = (x-5.5)/36

36*tan(25) = x-5.5

x-5.5 = 36*tan(25)

x = 36*tan(25)+5.5

x = 22.28707569358

x = 22.3 ft is the approximate height of the flagpole

Make sure your calculator is in degree mode.

The height is not over 25 ft, so this flagpole meets the requirements.

AC=4, AE=7, AD=10, what is the length of AB? <br> A: 1 3/7 <br> B: 2 1/2<br> C: 5 5/7<br> D: 17 1/2

Answer:

C. AB = 5\frac{5}{7}

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, \frac{AE}{AC} = \frac{AD}{AB}

\frac{7}{4} = \frac{10}{AB}

Cross multiply

7*AB = 10*4

7*AB = 40

Divide both sides by 7 to find AB

\frac{7*AB}{7} = \frac{40}{7}

AB = \frac{40}{7}

AB = 5\frac{5}{7}

Mel received notice that his monthly health care rate will increase 15% next year. if mel currently pays $200 per month for heal
Volgvan
Multiply 200 by .15, since 15% is .15 as a decimal. 200 x .15 = 30. This means that his health care rate will increase by $30 next year.

Mum bought a litre of orange juice. She filled 5 glasses and had 1/5 of a litre left. How much was in each glass?
avanturin [10]
1/5 of a litre is 0.2 litres
1 litre minus 0.2 litres is 0.8 litres so
0.8 divided by 5 (glasses) is 0.16 litres in each glass
