Answer:
112.2ft
Step-by-step explanation:
As can be seen in the attached diagram, The top of the building is at C.
The distance from the man to the building is |BD| and the height of the man is |AB| where his eye level is at B.
We are required to find the height |CE| of the building.
Now |AB|=|DE|, (opposite sides of a rectangle).
Tan 65° = |CD|/59
|CD|=59 XTan65°=107.23
The height of the building |CE|=|CD|+|DE|=107.23+5=112.23ft
The height=112.2ft ( to the nearest tenth)

Answer:
y = -(2/3)x + 3
C
Step-by-step explanation:
The slope of the equation that was given is - 2/3
The slope in a slope intercept equation is the number in front of the x when the value of the number in front of the y = 1 and x and y are on opposite sides of the equal sign. Let's translate that.
The original equation is y = -(2/3)x + 5/3
- y and x have to be on opposite sides of the equal sign [They are]
- The slope is the number in front of the x. That's (-2/3). That makes A incorrect.
Now you need to use the given point
The point is (-3 , 5) Put this into the equation that you have so far
y = (-2/3)x + b
y = 5
x = -3
5 = (-2/3)(-3/1) + b Substitute in the givens
5 = (-2 * -3)/3 + b Multiply -2 * - 3 = 6
5 = 6/3 + b Divide the 6 by 3
5 = 2 + b Divide
5 - 2 = b Subtract 2 from both sides
3 = b Switch sides
b = 3
Answer y = (-2/3)x + 3 or C
Answer:
i don't know if this is what you are needing but hoping it helps
Answer A is y = -3 because it
