Answer:
![x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}](https://tex.z-dn.net/?f=x_%7B1%7D%3D%5Cfrac%7B%2B3%2B%5Csqrt%7B5%7D%20%7D%7B2%7D%5C%5C%5C%5Cx_%7B2%7D%3D%5Cfrac%7B%2B3-%5Csqrt%7B5%7D%20%7D%7B2%7D)
Step-by-step explanation:
Using:
![x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%2B-%5Csqrt%7Bb%5E%7B2%7D-4%2Aa%2Ac%7D%20%7D%7B2%2Aa%7D)
we will have two solutions.
x^2-3x+1=0
So, a=1 b=-3 c=1
![x_{1}=\frac{+3+\sqrt{-3^{2}-4*1*1} }{2*1}\\\\x_{2}=\frac{+3-\sqrt{-3^{2}-4*1*1} }{2*1}](https://tex.z-dn.net/?f=x_%7B1%7D%3D%5Cfrac%7B%2B3%2B%5Csqrt%7B-3%5E%7B2%7D-4%2A1%2A1%7D%20%7D%7B2%2A1%7D%5C%5C%5C%5Cx_%7B2%7D%3D%5Cfrac%7B%2B3-%5Csqrt%7B-3%5E%7B2%7D-4%2A1%2A1%7D%20%7D%7B2%2A1%7D)
We have two solutions:
![x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}](https://tex.z-dn.net/?f=x_%7B1%7D%3D%5Cfrac%7B%2B3%2B%5Csqrt%7B5%7D%20%7D%7B2%7D%5C%5C%5C%5Cx_%7B2%7D%3D%5Cfrac%7B%2B3-%5Csqrt%7B5%7D%20%7D%7B2%7D)
Answer:
none
Step-by-step explanation:
We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.
According to the 'Law of Sines- Ambiguous Case', we have,
If a < b×sinA, then no triangle is possible.
If a = b×sinA, only one triangle is possible
If a > b×sinA, two triangles are possible.
So, we have,
b×sinA = 10 × sin30 = 10 × 0.5 = 5.
Now, as
4 = a < bsinA = 5.
We get, according to the rule, no triangle is possible.
