There's a 8ft. long board and the carpenter cut off 3 1/2 and 2 1/3.
So first we need to add 3 1/2 and 2 1/3 because the carpenter cut them off the 8ft. long board.
3+2=5 because it's a whole number. 1/2+1/3= 2/6+3/6= 5/6
5 5/6
Now we subtract
8-5 5/6=
7 6/6- 5 5/6= 2 1/6ft.
2 1/6ft. is what remains of the 8ft. board.
Answer:
The distance you are from the base of plateau = 
Step-by-step explanation:
Given:
Height of plateau = 70 m
Angle of elevation to the top of plateau = 35°
To find the distance you are from the base of plateau.
We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.
We will apply trigonometric ratio to find the adjacent side.

where
represents the angle of reference.
Plugging in the values from the triangle.


Multiplying both sides by AC.


Dividing both sides by 

∴ 
The distance you are from the base of plateau = 
Answer:
tanC will be given by the opposite over the adjacent
tanC=24/32
simplified to 6/8
