Answer:
3rd option
Step-by-step explanation:
You can divide 73/641 to find the percent:
73/641 = 0.11388455...
It keeps going on so I'll stop there.
Now to make it into a percentage, multiple it by 100:
0.11388455 * 100 = 11.388455%
A. is 21.98 cm
b. is 22 cm
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.
