Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is
![\frac{1}{2} \times base \times height](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20base%20%5Ctimes%20height)
our base and height are 6 for both triangles, so we shall find the area of one of the triangles...
![\frac{1}{2} \times 6 \times 6 = 18](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%206%20%5Ctimes%206%20%3D%2018)
multiply this by 2
![2 \times 18 = 36](https://tex.z-dn.net/?f=2%20%5Ctimes%2018%20%3D%2036)
Now find the area of the whole circle
![area = \pi {r}^{2}](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20)
our radius is 6, therefore:
![area = \pi {6}^{2} = 113.1](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%20%7B6%7D%5E%7B2%7D%20%20%3D%20113.1)
Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer
![113.1 - 36 = 77.1](https://tex.z-dn.net/?f=113.1%20-%2036%20%3D%2077.1)
Answer:
12 weeks
Step-by-step explanation:
if he wants 200 after the summer, 500-200=300
which means he can spend 300 dollars
25 goes into 100 4 times, which makes 100
another 4 times makes 200
and another 4 makes 300
add all the 4s to get your total of 12
now to make sure your right you can do 12×25=300
You're welcome. hope I'm giving you the right answer, have a blessed day:)
Answer:
-76/8 = -19/2
In an arithmetic sequence, the nth term, an, is given by the formula:
an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.
So, a9 = a1 + 8d
Substituting in the given data, 12 = 88 + 8d
-76 = 8d
d = -76/8 = -19/2

Answer:
B = 15.1°, C = 34.9°, c = 39.6
Step-by-step explanation:
law of sines
53/sin 130 = 18/sin B
sin B = .26; B = 15.1°
C = 180 - 15.1 - 130 = 34.9°
c/sin 34.9 = 53/sin 130
c = 39.6
