Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

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

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

patriot [66]

Answer:

-4y=11x-33

Step-by-step explanation:

3x-2y-16=-17+14x+2y

-2y-2y=14x-3x-17+16

-4y=11x-33
