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

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

If f(x)= - 4x-4, g(x)= 4x² + 4x + 2, and h(x)= 3x2 – 3, find f(3).

Deffense [45]

Answer:

$f(3) = -16$

Step-by-step explanation:

Given

$f(x)= - 4x-4$

$g(x)= 4x^2 + 4x + 2$

$h(x)= 3x^2 - 3$

Required

$f(3)$

We have:

$f(x)= - 4x-4$

Substitute $x = 3$

$f(3) = -4 * 3 - 4$

$f(3) = -12 - 4$

$f(3) = -16$

Hence:

$f(3) = -16$
