Answer: First option: 800 feet
Solution:
Height: h=400 sqrt(3)
Distance between the zoo and the point in the ground below the helicopter: d1=?
Distance between the library and the point in the ground below the helicopter: d2=?
Distance between the zoo and the library: d=?
d=d2-d1
tan 60°= h/d1
sqrt(3)=400 sqrt(3) / d1
Solving for d1:
sqrt(3) d1 = 400 sqrt(3)
d1= 400 sqrt(3) / sqrt(3)
d1=400
tan 30°= h/d2
sqrt(3) / 3=400 sqrt(3) / d2
Solving for d2: Cross multiplication:
sqrt(3) d2 = 3 [ 400 sqrt(3) ]
sqrt(3) d2 = 1,200 sqrt(3)
d2= 1,200 sqrt(3) / sqrt(3)
d2=1,200
d=d2-d1
d=1,200 feet - 400 feet
d=800 feet
I really don't know........ :);

Question B Would Either Be 99 Or -99 But Im Positive That Its 99.
The expressions are:
- (5x² - 6)/ 2
- 5x² - 18/2
- 5x² -6 /2
<h3 /><h3>What is expression?</h3>
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
- An absolute numerical number is referred to as a constant.
- Variable: A symbol without a set value is referred to as a variable.
- Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
- Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.
Given:
15 x squared minus 18 end quantity over 6.
= 15x² - 18 / 6
= 3(5x² - 6)/ 6
= (5x² - 6)/ 2
and, 5 x squared minus 18 end quantity over 2
= 5x² - 18/2
and, 5 x squared minus 6 end quantity over 2
= 5x² -6 /2
