Answer:

I don't use Geogebra, but the following procedure should work.

Step-by-step explanation:

Construct a circle A with point B on the circumference.

  1. Use the POINT and SEGMENT TOOLS to create a circle with centre B and radius BA.
  2. Use the POINT tool to mark points D and E where the circles intersect.
  3. Use the SEGMENT tool to draw segments from C to D, C to E, and D to E.

You have just created equilateral ∆CDE inscribed in circle A.

A flagpole is 20 feet tall is casting a shadow that is 8.2 feet long at what angle is the sun hitting the ground
Novay_Z [31]

Answer:

∅ = 67.71°

Step-by-step explanation:

The flag pole is 20 ft tall is casting a shadow that is 8.2 ft long .At what angle is the sun hitting the ground. The illustration forms a right angle triangle.

The right angle triangle has an hypotenuse, opposite and adjacent sides. The flag height forms the opposite side. The shadow forms the adjacent side . The angle the sun is hitting the ground can be using SOHCAHTOA principle.

using Tan

tan ∅ = opposite / adjacent

tan ∅ = 20/8.2

tan ∅ = 2.4390243902

∅ = tan⁻¹ 2.4390243902

∅ = 67.7063708403

∅ = 67.71°

Diana has 1 square yard of fabric she will make one pillow that requires 3/8 square yard of fabric and another pillow that requi
Scilla [17]

Answer:

<h2>Diana uses 5/8 square yard of fabric for both pillows.</h2><h2>There remains 3/8 square yard of fabric.</h2>

Step-by-step explanation:

Givens

  • The total amount of fabric is 1 square yard.
  • One pillow requires 3/8 square yard of fabric.
  • A second pillow requires 2/8 square yard of fabric.

To find the total amount of fabric Diana used, we must sum those fractions

\frac{3}{8} +\frac{2}{8}=\frac{5}{8}

Diana uses 5/8 square yard of fabric for both pillows.

Now, we subtract to find the remaining amount of fabric

1-\frac{5}{8}=\frac{8-5}{8}=\frac{3}{8}

Therefore, there remains 3/8 square yard of fabric.

a car rents for $40 per day plus 21 cents per mile. you are on a daily budget of $82. what mileage will allow you to stay within
pav-90 [236]

Answer:

200 miles will allow to stay within the budget

Step-by-step explanation:

∵ The daily budget is 82

∵ The cost per mile is 21/100 = $0.21

∵ The number of miles is x

∴ The equation of the budget is:

∴ 82 = 40 + 0.21 x

∴ 0.21 x = 82 - 40

∴ 0.21 x = 42

∴ x = 42/0.21 =200

∴ The number of miles = 200 to stay in the daily budget
