The possible outcomes where the red die shows a 3 are: (red, blue) = (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6).
angle at a straight line is =180
4+5+x=180
let x be angle at the tower
9+x=180
x=180-9
x=171°
and x is divide in to two then is 2x
there for
2x=171°
x=171/2
x=85.5°
then sin85.5°= 90/y
let y be the unknown feet
0.9969=90/y
y0.9969=90
y=90/0.9969
y=90.3ft.
You have to find the common denominator first, which is 68, then you do the math
12/17 is equal to 48/68
and, 3/4 is equal to 51/68
so, 51 is larger than 48
therefore, 3/4 is larger than 12/17
