The lengths of the sides of a triangle are consecutive integers, and the largest angle is twice the smallest angle. What is the
hjlf

Answer:cosA = \frac{a+2}{2a}

Step-by-step explanation:

Given that the lengths of the sides of a triangle are consecutive integers

Since side cannot be negative we can assume that the sides are

a, a+1 and a+2 where a>0

The largest angle is opposite side a+2 and smallest is angle opposite a

Using sine formula and the given information that the largest angle is twice the smallest angle

we get

\frac{a}{sin A} =\frac{a+2}{sin 2A}

Cross multiply to get

\frac{sin 2A}{sin A } =\frac{a+2}{a}

Since sin 2A = 2sin A cos A

we get

2cosA = \frac{a+2}{a} \\cosA = \frac{a+2}{2a}
