The closer Diana gets to the building, the smaller the angle becomes
Diana is 17.6 feet closer to the building
<h3>How to calculate the distance from the building</h3>
To calculate the distance between her and the building, we make use of the following tangent ratio
Where:
- h represents the height of the building; h = 130
- d represents the distance from the building
So, we have:
Make d the subject
Evaluate tan(40)
Initially, Diana is at a distance of 172.53.
The difference in both distance is:
Hence, Diana is 17.6 feet closer to the building

Answer:
The equation of straight line is x = 1
Step-by-step explanation:
<u>Step </u>:-
The equation of straight line having slope 'm' and passing through the point
is 
Slope of horizontal line(that is x-axis) is m = 0
slope of vertical line (that is y-axis) is m is not defined
The equation of straight line having slope is not defined and passing through the point (1,7).
cross multiplication we will get equation
x-1 = 0
The equation of straight line is x = 1
Answer:
b and d
Step-by-step explanation:
<u>Answer:</u>
are two roots of equation 
<u>Solution:</u>
Need to solve given equation using quadratic formula.
General form of quadratic equation is 
And quadratic formula for getting roots of quadratic equation is
In our case b = -1 , a = -3 and c = -3
Calculating roots of the equation we get
Since 
is equal to -35, which is less than zero, so given equation will not have real roots and have complex roots.
