Answer:
72, 144, 216, 288
Step-by-step explanation:
A geometric figure has rotational symmetry if the figure appears unchanged after a rotation about a point by an angle that is between 0° and 360°. 0° and 360° are excluded since they represent the original position, nothing new happens. The angles of rotational symmetry will be factors of 360.

The question is an illustration of a division model.
The boxes will be completed with: 1650, 231, 50 and 7
The expression is represented as:
Express 1881 as 1650 + 231.
Split
Evaluate each division
The above illustration means that, the boxes will be completed with the following numbers

Answer: The angle of elevation is 18.4 degrees (Approximately)
Step-by-step explanation: Please refer to the picture attached for more details.
The pole from top to bottom is 20 feet tall and is depicted as line FB. An observer is standing at a distance of 20 feet from the base of the pole, and that is depicted as line BA. The observer who is at point A looks up to the top of the flagpole at an angle of elevation shown as angle A.
Using angle A as the reference angle, line FB which is 20 feet would be the opposite (facing the reference angle), while line BA which is 60 feet would be the adjacent (that lies between the right angle and the reference angle).
Therefore, to calculate angle A;
Tan A = Opposite/Adjacent
Tan A = 20/60
Tan A = 1/3
Tan A = 0.3333
Checking with your calculator or table of values,
A = 18.4349°
Rounded to the nearest tenth,
A ≈ 18.4°
Answer:
1)
2)
Step-by-step explanation:
You can convert he mixed numbers to improper fractions:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained to the numerator.
3. The denominator does not change.
Then:
Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:
Divide 15 by 4. The quotient will be 3 and the remainder 3.
Then:
