In the given triangle, the angle between the two sides 5 and 6 is nearest 41°.
The term triangle means the polygon which has three sides and three angles and three vertices,
Here we have given that three sides of a triangle have lengths 4, 5, and 6.
And here we need to find the angle between the two sides 5 and 6
According to the given values, let us consider a = 4, b = 5 and c = 6
So, the angle between 5 and 6 can be written as ∠b
And it can be calculated as the following is one way to perform the calculation and it may not be the best way.
∠B = arc cos(a² + c² - b²)/2ac
When we apply the values one the formula, then we get
=> 0.72273 rad
The approximate degree is written as
=> 41.41°
When we round off it then we get the resulting value,
=> 41°
Therefore, option (c) is correct.
