Answer:
The tree is 20.6 ft tall.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.
The diagram makes a right-angled triangle.
- Given the angle = Ф = 38⁰
- Hypotenuse = Tree length = c ?
Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:
substituting a=5, b=20
ft
Thus, the tree is 20.6 ft tall.
Answer:
A
Step-by-step explanation:
the triangles share one angle and they have two equal sides
Answer:

Answer:
385 hamburgers.
Step-by-step explanation:
So the data they have given us is that there have been 2 home games, with 70 hamburgers sold. If we divide the number of hamburgers sold by the number of games (70/2), we come up with the average hamburgers sold per game, which is 35. We can use an equation to find the amount of hamburgers sold for every x amount of games. , with x being the amount of games, and h being the total amount of hamburgers. If you plug in 11 for x, you will get 385.
Well. The formula for the area of a trapezoid is b1 + b2 over 2 times h.
a = b1 + b2 (h)
