ANSWER
x=39.86
If you increase a number by 4.5%, then you're adding 4.5% of that number to 100% of that number. So essentially you just multiply 14187.13 by 104.5%, or 1.045 to find the answer, which is 14,825.55.
Formula of the line
y=mx+b.
For parallel line slope m is the same, so m= -2.
y=-2x+b.
We need to find b,using the point (3,1).
1= - 2*3+b
b=7
y = -2x +7
Answer is A. y = -2x +7.
Answer:

Step-by-step explanation:
Given that,
The height of a cell tower, P = 70 m
The tower casts a shadow of 45 meters on the ground.
We need to find the angle of elevation of the shadow to the top of the cell tower. We can use trigonometry to find it.

Put all the values,

Hence, the angle of elevation is equal to
.
