The answer is the option b. 1.
Two sides and one angle determine one unique triangle.
If the angle is the between the two sides, you just can use the rule known as SAS, Side Angle Side.
When that is the case you use the cosine rule.
When the known angle is not between the two sides but one of the others, you use sine theorem.
Then in any case when you know two sides and one angle of a triangle the other side and angles are determined, which implies that there is only one possible triangle.
Answer:
Removing the perfect square 4 in 12 we get 2√3
Step-by-step explanation:
The square root of 12 is
√12 = √(4 x 3)
√12 = 2√3.
There's no special trick here, but it's usually easy to check whether a small number is divisible by 4. Keep this in mind when looking for factors.
Removing the perfect square 4 in the square root of 12 we get 2√3.
Here 4 is a perfect square it can be written as
√4 =√2^2
√4 =2
