<u>Answer:</u>
The correct answer option is B. 72°.
<u>Step-by-step explanation:</u>
A polygon is said to be a regular polygon when all its sides and angles are equal.
So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.
When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.
Therefore, option B is the right choice.
Using the Pythagorean theorem we can solve for x.
x^2 + 6^2 = 10^2
Simplify:
x^2 + 36 = 100
Subtract 36 from both sides:
x^2 = 64
x = √64
x = 8
Answer:
A
Step-by-step explanation:
The values will increase because the multiplier is greater than 1 (1.05).
Answer:
B
Step-by-step explanation:
Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are
A) 64 - 72.25
B) 72.25 - 81.
74 falls between 72.25 - 81. So it'll be B
The Great common factor is 3.
So divide both numerator and denominator by 3 and you have -5.2.
