- $6.88
- 2.5 pounds
Step-by-step explanation:
1. In this case, it appears that "some" means "4". The total cost of 4 place mats and 4 napkin rings is apparently ...
$17.16 +10.36 = $27.52
Then the total cost of 1 of each is 1/4 this amount, or ...

Answer:
The height of the statue is <u>21.4 feet.</u>
Step-by-step explanation:
Given:
Distance of the person from the statue = 50 ft
Angle of elevation of the top of statue = 16°
Angle of depression of the bottom of statue = 8°
The diagram is drawn below.
In triangle ABC:
BC = 50 ft, ∠ABC = 16°
Using trigonometric formula;
Now, let us determine the height of man, 'x'.
Consider triangle BDE.
ED = 50 ft, ∠BDE = 8°
Using trigonometric formula;
Now, from the diagram, it is clear that, height of statue is given as:
2,4,44 because the gathing numbers are equal to represent
Number 15 is c and number 16 is a
