Answer:
![r=\frac{6\sqrt{10AS}}{S\sqrt{\pi }}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B6%5Csqrt%7B10AS%7D%7D%7BS%5Csqrt%7B%5Cpi%20%7D%7D)
Step-by-step explanation:
Given the formula;
![A=\frac{\pi r^2S}{360}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20r%5E2S%7D%7B360%7D)
We want to solve the given formula for r.
Multiply both sides by ![\frac{360}{\pi S}](https://tex.z-dn.net/?f=%5Cfrac%7B360%7D%7B%5Cpi%20S%7D)
![A\times \frac{360}{\pi S}=\frac{\pi r^2S}{360} \times \frac{360}{\pi S}](https://tex.z-dn.net/?f=A%5Ctimes%20%5Cfrac%7B360%7D%7B%5Cpi%20S%7D%3D%5Cfrac%7B%5Cpi%20r%5E2S%7D%7B360%7D%20%5Ctimes%20%5Cfrac%7B360%7D%7B%5Cpi%20S%7D)
![A\times \frac{360}{\pi S}=r^2](https://tex.z-dn.net/?f=A%5Ctimes%20%5Cfrac%7B360%7D%7B%5Cpi%20S%7D%3Dr%5E2)
Take square root of both sides
![r=\sqrt{\frac{360A}{\pi S}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%5Cfrac%7B360A%7D%7B%5Cpi%20S%7D%7D)
![r=\frac{\sqrt{360A}}{\sqrt{\pi S}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5Csqrt%7B360A%7D%7D%7B%5Csqrt%7B%5Cpi%20S%7D%7D)
![r=\frac{\sqrt{360A}}{\sqrt{\pi }\sqrt{S}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5Csqrt%7B360A%7D%7D%7B%5Csqrt%7B%5Cpi%20%7D%5Csqrt%7BS%7D%7D)
![r=\frac{\sqrt{360A}\times \sqrt{S}}{\sqrt{\pi }\sqrt{S} \times \sqrt{S}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5Csqrt%7B360A%7D%5Ctimes%20%5Csqrt%7BS%7D%7D%7B%5Csqrt%7B%5Cpi%20%7D%5Csqrt%7BS%7D%20%5Ctimes%20%5Csqrt%7BS%7D%7D)

Answer:
7x + 33 -I could be wrong I'm not an expert in maths jus trying to help
Step-by-step explanation:
x + 13 9x-7
so first you need to times both by two because there are two of both sums
2(x+13) so you times both numbers by 2 so
= 2x+26
and do the same with 9x - 7 so
2(9x-7) = 18x - 14
and then you add them together and find the like terms.
Like terms means for example in the equation:
2x + 3x - 4 + 3
the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.
In this case its:
2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.
So 2x + 5x = 7x and 26 + 7 = 33.
So the final equation is 7x + 33
Hope this helps :D
Answer:
1.
a = 112
b = 68
c = 68
2.
a = 127
3.
a=35
b=40
c=35
d=70
4.
a= 30
b=70
c = 30
d=70
e = 130
I'll help you with the rest later
Step-by-step explanation:
a = 112 because of allied angles rule
b and c = 68 because of angles at a point
360-112-112 ÷2
2. a = 127 because of angles on a straight line rule.
180-38-15
3. d= 70, vertically opposite angle
using angles on a straight line, 180 - 70 - 40 ÷ 2
we now have the two angles and because they are vertically opposite a and c = 35
b = 40 because of vertically opposite angles
4. a=30 because 90-70
since a=30, take 90 - 30 to get b, 70
d= 70, vertically opposite angles
e = 130 because a+b+c, vertically opposite angles
