Problem 1

Draw a straight line and plot P anywhere on it. Use the compass to trace out a faint circle of radius 8 cm with center P. This circle crosses the previous line at point Q.

Repeat these steps to set up another circle centered at Q and keep the radius the same. The two circles cross at two locations. Let's mark one of those locations point X. From here, we could connect points X, P, Q to form an equilateral triangle. However, we only want the 60 degree angle from it.

With P as the center, draw another circle with radius 7.5 cm. This circle will cross the ray PX at location R.

Refer to the diagram below.

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

Problem 2

I'm not sure why your teacher wants you to use a compass and straightedge to construct an 80 degree angle. Such a task is not possible. The proof is lengthy but look up the term "constructible angles" and you'll find that only angles of the form 3n are possible to make with compass/straight edge.

In other words, you can only do multiples of 3. Unfortunately 80 is not a multiple of 3. I used GeoGebra to create the image below, as well as problem 1.

Whitepunk [10]

Step-by-step explanation:

given

5 t-shirts = R120

(5÷5) t - shirt = R(120÷5)

1 t-shirt = R24

(1x9) t-shirts = R(9x24)

= R216

Marie has a part time job. She earns $7 an hour. She makes at most $143.50 per week. What is the greatest number of hours that s
Troyanec [42]
We can divide 143.50 by 7. This gives us 20.5. This means that she works 20.5 hours a week or 21 hours if you round up.

A teacher is cutting pieces of tape for the marshmallow challenge.The roll of tape is 16.8 meters long and each piece measures 1
Zanzabum

Given:

Total length of tape in roll = 16.8 meters

Length of each piece = 1.125 meters

Number of pieces = 8

To find:

The remaining tape.

Solution:

We have,

Length of 1 piece = 1.125 meters

Length of 8 piece = 8 × 1.125 meters

                              = 9 meters

Total length of tape in roll = 16.8 meters

Remaining tape = Total length of tape in roll - Length of 8 piece

                           = 16.8 - 9 meters

                           = 7.8 meters

Therefore, the length of remaining tape is 7.8 meters.
