Answer: A(y=x/2)
Direct variation describes the relationship between the two variables
4a-[7-2(a+6)+5a]
4a-[7-2a-12+5a] :you distribute the 2 to the a and the 6
4a-[-5+3a] :you combine like terms(the 7&(-12) and the 2a&5a
4a+5-3a :you distribute the (-) to make +5 and -3a
a+5
The cables are 5,060.567 ft
You use tan to find this because 5000 is the opposite and your are trying to find the adjacent to the angle so then you can do Pythagorean theorem to find the length of the cables
Tan(30)=5000/x
Multiply x on both sides
X•tan(30)=5000
Divide by tan(30)
X= 5000/ tan(30)
X= -780.5997608
Then you plug it in because x is the bottom length of the right triangle and now your finding the hypotenuse, the length of the cables
-780.5997608^2 + 5000^2 = x^2
609,335.9866 + 25,000,000= x^2
25,609,335.99 =x^2
Then you square root the number
And x = 5,060.566766 ft
And your just round to the nearest hundredth or tenth like it did up too
Answer:
so if r is a right angle and its wants us to prove that ab =1/2pq the answer would be
