Angles of rotation that would not map the shape on itself
Side of a nonagon is:
and a complete rotation is:
To start with, we calculate a possible angle of each rotation:
This is calculated by dividing the complete rotation by number of sides
The question lacks option; so, it's difficult to give a specific answer.
However, I'll give a generalized answer
For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)
i.e.
<em>Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.</em>
Answer:
Current points on Ken's card = 58
Step-by-step explanation:
Given:
Reward card points to be earned in order to be offered a free smoothie =75
Ken is in need of 17 more points to win a free smoothie.
∴ The current points on Ken's card must be =
We assume , A, B, and C are angles of a triangle.
The sum of angles of a triangle is equal to 180º; therefore:
A+B+C=180º
B is 45% of angle A; then B=0.45A
C is 35% of anble A; Then C=0.35A
We can suggest this equation;
A+0.45A+0.35A=180
1.8A=180
A=180/1.8
A=100
Answer: The measurement of angle A is 100º.
Answer:
22
Step-by-step explanation:
4x = 6x-44
1. Set x as the number we want to find.
2. Multiply by four (this makes one side of the equation)
3. "Is" tells us that 4x will be set equal to another expression.
4. The expression "6 times the number" tells us that we need to multiply 6 by x: 6x.
5. We now must account for the "44 less than 6 times the number", less than indicates subtraction. We are told that 44 fewer units than 6x will define this function.
6. 6x-44
7. Now set 4x=6x-44 (this goes back to step 3)
8. Use algebra to solve, first we want to isolate x, so subtract 6x on both sides.
9. -2x=-44 Now divide by -2 on both sides.
10. You reach an answer of x=22.
