Answer:
6.13
Step-by-step explanation:
Using Sine Law we know that
![\dfrac{a}{SinA}=\dfrac{b}{SinB}=\dfrac{c}{SinC}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%7D%7BSinA%7D%3D%5Cdfrac%7Bb%7D%7BSinB%7D%3D%5Cdfrac%7Bc%7D%7BSinC%7D)
Using your figure let's assign sides and angles:
A=? B = 60° C = 70°
a = 5 b = ? c = x
If we put that into our formula:
![\dfrac{5}{Sin?}=\dfrac{?}{Sin60}=\dfrac{x}{Sin70}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7BSin%3F%7D%3D%5Cdfrac%7B%3F%7D%7BSin60%7D%3D%5Cdfrac%7Bx%7D%7BSin70%7D)
Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?
Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°
∠A + ∠B + ∠C= 180°
∠A + 60° + 70° = 180°
∠A + 130° = 180°
∠A = 180° - 130°
∠A = 50°
Now we can use this to solve for x.
![\dfrac{5}{Sin50}=\dfrac{x}{Sin70}\\\\\dfrac{(5)(Sin70)}{Sin50} = x\\\\\dfrac{4.6985}{0.7660}=x\\\\6.1338 =x](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7BSin50%7D%3D%5Cdfrac%7Bx%7D%7BSin70%7D%5C%5C%5C%5C%5Cdfrac%7B%285%29%28Sin70%29%7D%7BSin50%7D%20%3D%20x%5C%5C%5C%5C%5Cdfrac%7B4.6985%7D%7B0.7660%7D%3Dx%5C%5C%5C%5C6.1338%20%3Dx)
So the closest answer would be 6.13
Answer:
Step-by-step explanation:
Yes. because In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers
Answer:
The best fit line is ![y = 1.671x + 4.699](https://tex.z-dn.net/?f=y%20%3D%201.671x%20%2B%204.699)
Step-by-step explanation:
We are given,
The table representing the number of miles run in different weeks is,
Week Miles Run
1 5
2 8
4 13
6 15
8 19
10 20
Using the linear regression calculator, we see that,
<h3>The equation of the line best fit for the data is
![y = 1.671x + 4.699](https://tex.z-dn.net/?f=y%20%3D%201.671x%20%2B%204.699)
.</h3>
