Answer:
x = 14.7
Step-by-step explanation:
Using the sine rule

Substitute the given values.

Rearrange the equation to get x on it's own.

x = 14.72246211
x = 14.7 (1dp)
let's recall that corresponding angles are equal, thus 105° twins, also let's recall that a flat-line has 180°.
since the two sides stemming from Ɣ are twins, the angles they make at the base are also twins, bearing in mind that a triangle has a sum of all interior angles of 180°.
Answer:
31,250 ft²
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the ends of the rectangle will have dimesion (500-x)/2, and the total area will be ...
... A = x(500-x)/2
This function describes a parabola with zeros at x=0 and x=500. The vertex (maximum) will be located halfway between these, at x=250.
The maximum size pen has area ...
... A = 250(500 -250)/2 = 31,250 . . . . sq ft
Answer:
There are 5,586,853,480 different ways to select the jury.
Step-by-step explanation:
The order is not important.
For example, if we had sets of 2 elements
Tremaine and Tre'davious would be the same set as Tre'davious and Tremaine. So we use the combinations formula.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In how many different ways can a jury of 12 people be randomly selected from a group of 40 people?
Here we have
.
So

There are 5,586,853,480 different ways to select the jury.
