Answer:
#3
20tan(53) + 5 feet OR 31.54 feet (rounded to nearest hundredth)
#4
6tan(32) feet OR 3.75 km (rounded to nearest hundredth)
Step-by-step explanation:
#3
The horizontal line is at Chloe's eye level, which is 5 feet.
She looks up at an angle of 53 degrees, and is 20 feet away from the statue. This creates a right triangle that you can use basic trigonometry to solve.
Let's call the shorter leg (upper half of statue) as x and the longer leg (distance between Chloe and statue) is 20 feet. We are given the opposite and adjacent sides (from the given angle) so we can use tan.
tan = opp/adj, so tan(53)=x/20
If you plug 20 tan 53 into your calculator to find x, you get 26.54089643
But you have to add 5 feet to your answer because that is her eye level.
#4
The horizontal distance from airplane to raft is 6km, the angle of depression is 32 degrees from the airplane, and we are asked to find the altitude of the plane (x).
We are given an adjacent side and are tasked to find the opposite side, so we will use tan.
tan 32=x/6
Plug this into your calculator and you get x=3.749216111 km.
It would be 12x-3y because 10 + 2 is 12
Answer:
The answer is C.
Step-by-step explanation:
They don't explain how to find the total distance Candice ran.
Answer:
B-Tickets
B-15x-500≥1000
C-x≥100
Step-by-step explanation:
X is the variable because you need to find how many tickets need to be sold
The answer is B because they need to raise $1000 or more
15x-500≥1000 (add 500 to both sides)
15x≥1500
x≥100
