The probability for not rolling a five would be 5 out of 6 times (5/6).
Let AB the length of the lighthouse, with A, its foot and AC the distance from the foot of the lighthouse to the ship.
The angle of depression = to angle BCA (alternate interior)
tan (BCA) = 88/1532
tan (BCA) = 22/383 = 0.0574413
tan⁻¹(0.0574413) = 3.287 = 3.29" (3rd Answer)
10 + 10 + 10 = 30
2 = 2
32/5
average speed per hour is 6.4 mph
2.
for perimeter, add the lengths and widths
for area, multiply the length by the width
So, the perimeter is 6+6+5+5
=22
the area is 6 times 5
=30
Lying in the same straight line i think..
