Answer:
Step-by-step explanation:
The rectangle has been split into two right triangles. The hypotenuse of the triangle (the diagonal) is 18. The angle in the triangle is 30. All right triangles have unique relationships between their sides depending on the angles. This triangle must be a 30 - 60 - 90 triangle and its sides will be a scaled version of 
.
The side 2 correspond to the hypotenuse of length 18. 2*9 = 18 and so the scale factor is 9. To find the remaining sides, multiply each side length by 9 from .
It becomes 
. So the rectangle is 9 by 
.
The perimeter of the rectangle is 
Answer:
2 : 1
Explanation:
<u>1st sector</u>:
<u>2nd sector</u>:
Ratio of 1st sector to 2nd sector:
44.68 : 22.34
2 : 1
Answer: 3(x)≥15 →x≥5
Step-by-step explanation:
Set it up with x as the number of days. Then multiply that by 3, so that you get 3(x). This will show that for an x amount of days, you ran 3 miles. then set it to MORE THAN or EQUAL TO 15. Then divide both sides by 3, and you get the above answer.
Okay, so, simply, the area of the hexagon would be <span>399.48 sq in
The perimeter would be </span><span>74.4 in</span>
Answer:
36
Step-by-step explanation:
plug in a=3 for a
I belive you meant 99- 7 * a^2
so 99- 7 * (3)^2 = 36
