EDIT: The answer I posted for the question is wrong, and I will fix it because i got confused this is all my fault xD Here is the correct way to solve it.
Ok, so first we have to find 1/8, 3/10, and 2/5 of 200.
I will just fastfoward that, and we get 1/8=25, 3/10=60, and 2/5=80.
(To find these, you multiply 200 by each fraction).
Next, we will add all the numbers, and we will get 165.
Remember, there is still one more season left, so we subtract 165 from 200 to get
the remaining amount of people who voted for winter.

Aproxx. 90 or 89 it was to long to type so im giving you the estiment
An equilateral triangle sides are all equal to each other. This means that is one side of an equilateral triangle is x + 3 then the sides of the other two triangles as also each x + 3
The formula for perimeter of a triangle is:
Perimeter = side 1 + side 2 + side 3
Or in the case of an equilateral triangle it would be:
Perimeter = 3(side)
This means that for the formula of this equilateral triangle you have:
Perimeter = 3(x + 3)
If asked the three out side of the parentheses can be distributed, meaning that you multiply the outside number (in this case that is 3) to all the number inside the parentheses (in this case that is x and 3)
Perimeter = (3 * x) + (3*3)
Perimeter = 3x + 9
Both of these are correct:
P = 3(x + 3)
P = 3x + 9
Hope this helped!

Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so ...
(2x +10)° +(3x -9)° +(6x -19)° = 180°
11x -18 = 180 . . . . . collect terms, divide by °
11x = 198 . . . . . . . . add 18
x = 18 . . . . . . . . . . . divide by 11
Then the angle of interest is ...
m∠T = (3x -9)° = (3·18 -9)°
m∠T = 45°
_____
The other angles are ...
m∠S = 46°
m∠U = 89°
Answer:
tan(330°) = (-√3)/3
Step-by-step explanation:
tan(330°) = tan(-30°) = -tan(30°) = -1/√3
The form with a rationalized denominator is ...
tan(330°) = (-√3)/3
