They will need 18 tokens each because 2 + 3 + 4 x 2 = 9
Do you mean "perpendicular to k"? We have no line c there so I'm going with line k. First we need the slope of line k. Fitting those values into the slope formula we have
. So the slope of k is 9. The slope of a line perpendicular to k has the opposite sign and the fraction is flipped. The perpendicular slope then is -1/9.
Answer:
Step-by-step explanation:
use the formula 
so you would get
Those negatives becomes a positive and you get 4+8 = 12 and 0+7 = 7
you final answer would be
Answer:
120°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 since a pentagon has 5 sides, thus
sum = 180° × 3 = 540°
let x be the measure of the 3 equal angles
Sum the interior angles and equate to 540
112 + 68 + 3x = 540, that is
180 + 3x = 540 ( subtract 180 from both sides )
3x = 360 ( divide both sides by 3 )
x = 120
Hence the measure of each equal interior angle is 120°
The volume can be found with this general formula:
V = area·height
To solve for area, divide height from both sides to get the area by itself:
V ÷ height = area
We know our values for the volume and height. Plug them into this equation:
V = 1,258 3/5
height = 11 3/5
1,258 3/5 ÷ 11 3/5 = 108.5
The area of the floor is 108.5 square meters.
