Answer: 
Step-by-step explanation:
The inradius is given by the area of the triangle divided by the semiperimeter.
The semiperimeter is
.
Thus, by Heron's formula, the area is
.
Therefore, the radius is 
8×.25=2
8-2=6
so what you would do is make a bar graph where the y axis would be years and the x axis being height
Hi there,
To compare we can look at the amount of (ounces)
A: 12 B:24
so as it appears B wins this part
Now price
A: $ 4.39 B:$2.79
A is relatively expensive than B
B is cheaper with more ounces
A is less ounces and relatively expensive
which one would you buy?
Answer:

Step-by-step explanation:
The given trigonometric equation is
.
We can either use the Pythagorean identity or the right angle triangle to solve for
.
According to the Pythagorean identity,

Recall that, the cosine function is an even function, therefore

.
We substitute this value in to the above Pythagorean identity to get;






But we were given that,
, so we choose the negative value.

The correct answer is B
