In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch
Answer:
72°
Step-by-step explanation:
Given
Zy = 108°
Zx = ?
We know
Zx + Zy = 180° {being supplementary angles }
Zx + 108° = 180°
Zx = 180° - 108°
Zx = 72°

Answer:
Each of the other cats have 45 whiskers on average.
Step-by-step explanation:
Let x represent the average number of whisker of each cat.
We have been given that there are 7 cats in my neighborhood, with an average of 41 whiskers each.
The total number of whiskers of six cats would be
.
Since one of the cats has 17 whiskers, so the total number of whiskers of 7 cats would be ![6x+17](https://tex.z-dn.net/?f=6x%2B17)
We will use average formula to solve our given problem.
![\text{Average}=\frac{\text{Sum of data points}}{\text{Number of data points}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%7D%3D%5Cfrac%7B%5Ctext%7BSum%20of%20data%20points%7D%7D%7B%5Ctext%7BNumber%20of%20data%20points%7D%7D)
Upon substituting our given values, we will get:
![41=\frac{6x+17}{7}](https://tex.z-dn.net/?f=41%3D%5Cfrac%7B6x%2B17%7D%7B7%7D)
Let us solve for x.
![41*7=\frac{6x+17}{7}*7](https://tex.z-dn.net/?f=41%2A7%3D%5Cfrac%7B6x%2B17%7D%7B7%7D%2A7)
![287=6x+17](https://tex.z-dn.net/?f=287%3D6x%2B17)
![287-17=6x+17-17](https://tex.z-dn.net/?f=287-17%3D6x%2B17-17)
![270=6x](https://tex.z-dn.net/?f=270%3D6x)
Switch sides:
![6x=270](https://tex.z-dn.net/?f=6x%3D270)
![\frac{6x}{6}=\frac{270}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%3D%5Cfrac%7B270%7D%7B6%7D)
![x=45](https://tex.z-dn.net/?f=x%3D45)
Therefore, the each of the other cats have 45 whiskers on average.
