-9y=-3x+216
y=1/3x-24
m=-3
y=-3x+16 is perpendicular to the line
[c] 70°
40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles
X(3)=30
(I hope this is right) ((sorry if it’s not))
The total possibilities is still 4.
H H
H T <<<<
T H <<<<
T T
The two that work are marked with <<<<
H T = 1/3 * 2/3 = 2/9
T H = 2/3 * 1/3 = 2/9
The total is 2/9 + 2/9 = 4/9
We should check this
1 heads = 4/9
2 heads = 1/9
2 tails = 4/9
4/9 + 4/9 + 1/9 = 1 It checks
