Answer:
Slope sides are;
5.07 m and 6.39 m
Step-by-step explanation:
I've attached a drawn diagram showing a triangle representing the roof slopes and I have attached it.
From the image attached, the missing angle is θ.
From sum of angles in a triangle,
θ = 180 - (44 + 34)
θ = 102°
Now, a & b represent the slopes of the roof.
Thus, using law of sines which is that;
a/sin A = b/sin B = c/sin C, we can solve as follows;
a/sin 34 = 9/sin 102
a = (9 × sin 34)/sin 102
a = (9 × 0.5512)/0.9781
a = 5.07 m
b/sin 44 = 9/sin 102
b = (9 × sin 44)/sin 102
b = (9 × 0.6947)/0.9781
b = 6.39 m

Step-by-step explanation:
the first song on the list could be 8 possible songs;
and the second song on the list could be 7 possible songs after the first one was set;
the third song on the list could be 6 possible songs after the first and second songs were set;;
the fourth song on the list could be 5 possible songs after the first ,second and third songs were set;;
the fifth song on the list could be 4 possible songs after four songs were set;
the sixth song on the list could be 3 possible songs after five songs were set;
the seventh song on the list could be 2 possible songs after six songs were set;
the eighth song on the list could be 1 possible songs after seven songs were set.
so THERE ARE 8X7X6X5X4X3X2X1 DIFFERENT SETS
