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

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

In a pen of goats and chickens, there are 40 heads. and 130 feet How many goats and chickens are there?

timama [110]

Answer:

25 goat and 15 chicken

Step-by-step explanation:

Say the number of goats is G, then the number of chickens is 40 - G as there are 40 heads and each chicken and each goat has one head.

The number of feet is 130

So 2(40 - G) + 4G = 130

So 80 - 2G + 4G = 130

2G = 50

G = 25

A baseball team consists of 2 stars, 13 starters, and 10 substitutes. For tax purposes, the team owner must value the players. T

inessss [21]

Answer:

The total value of the team=$8.2 million

Step-by-step explanation:

Step 1

Determine the total value of the team as follows;

V=(S×s)+(T×t)+(B×b)

where;

V=total value of the team

S=total value per star player

s=number of stars in the team

T=total value per starter

t=number of starters in the team

B=total value per substitute

b=number of substitutes in the team

In our case;

S=1 million per year

s=2 stars

T=400,000

t=13

B=100,000

b=10

replacing;

V=(1,000,000×2)+(400,000×13)+(100,000×10)

V=(2,000,000+5,200,000+1,000,000)

V=8,200,000=8.2 million

The total value of the team=$8.2 million
