Answer:
Marcus position: -18 meters
Step-by-step explanation:
We establish a reference system where the zero height is on the sea surface. Then all height below the sea surface is negative.

⊥ Marcus: - 18 meters
So the position of marcus is: -18 meters above sea level.
To return to the surface you must move 18 meters up.
Your answer would be -20 ft per sec/5 = -4 ft/sec
The larger angle is 55 deg at the larger angle.
We have to know which angles are called Complementary Angles...
if we add two angles and the total will be equal to 90 deg
let's say one angle is x and another angle is y
as they are complementary angles from the definition we can write the equation x + y = 90
one angle is 20 deg more than another one so from the above condition we write x = 20 + y
Substitute the value of x in the first eaquation we get, 20 + y + y = 90
Then, 20 + 2y = 90
subtracting 20 from both sides,
2y = 90-20 = 70
dividing both sides by 2,
2y/ 2 = 70 / 2
y = 35
So we got one angle is 35 deg
another angle is 35 + 20 = 55 deg.
Our answer is 55 deg the larger angle.
