Answer:
t = 1.41 seconds
Step-by-step explanation:
We know the height at which the coconut is, which is 64 ft, now assuming that we are on the ground, we know that gravity is equal to 32.1742 ft / s².
Gravity is an acceleration, we have that the acceleration is equal to:
a = v / t
but the speed v = d / t, replacing we have:
a = (d / t) / t
That is to say
a = d / t²
Now, solved for you we have:
t = (d / a) ^ (1/2)
Replacing the values, we are left with:
t = (64 / 32.17) ^ (1/2)
t = 1.41 seconds
therefore, the person has 1.41 seconds to escape.

Answer:
Step-by-step explanation:
In an isosceles trapezoid, two pairs of adjacent angles are supplementary. It means that the sum of the adjacent angles is 180°
Looking at the diagram, angle X and angle W are adjacent angles. It means that
X + W = 180
Since X = 105, then
105 + W = 180
W = 180 - 105 = 75°
Since W = b + 25°, then
b + 25° = 75
b = 75 - 25 = 50°
