Answer:
<em>180/7 deg and 1080/7 deg</em>
Step-by-step explanation:
The measures of two supplementary angles add to 180 degrees.
One angle measures x.
The supplement measures 6x.
The sum of the measures is 180 deg.
x + 6x = 180
7x = 180
x = 180/7
6x = 1080/7
Is the problem already solved or does it need to be simplify <span />
Wow...we have lots of numbers to go through. we know that a 6 sided figure is a hexagon and the interior angles add up to be 720°. so.....
∠A + ∠B + ∠ C + ∠D + ∠E + ∠F = 720°
(x - 60) + (x - 40) + 130 + 120 + 110 + (x - 20) = 720
3x + 240 = 720 (combined all like terms)
3x = 480 (subtracted 240 from both sides)
x = 160 (divided both sides by 3)
put the value of x into ∠A (x - 60) = 160 - 60 = 100
∠A = 100°
7% of x = 450
0.07×x=450
x=450/0.07
x=6428.6 to the nearest tenth (one decimal place)
There are 20 skirts in total and five of them are yellow.
The probability that she will pick a yellow skirt is 5/20 (simplifies to 1/4)
Multiply this by the probability that the coin will land on tails 1/2
1/4 x 1/2 =
1/8
Maria has a 1/8 chance that she will pick a yellow skirt AND land the coin on tails.
