Step-by-step explanation: Alright adding fractions here we go.
3 3/5 + 2 1/4
First add up the whole numbers. 3+2=5
Then adding the mix numbers, what you need to do is find a common demoninator. What do 5 and 4 both go into? Well 20, so we multiply each demoinator to get 20.
3/5+1/4
12/20 + 5/20
17/20

Answer:
69.282 m
Step-by-step explanation:
We can use the trigonometry of right triangles to solve this, since we are in the presence of a right triangle with acute angle 30 degrees, opposite side unknown (the vertical height of the cliff), and adjacent side equal to 120 m.
we use the tangent function to solve for the unknown, as shown below:
tan(30) = x/120
x = 120 * tan(30) = 69.282 m
