Well it's an arythmetic sequence, so it will look like:
Note that the first element is:
and the second element is:
So the difference between the two gives us d!
Now let's find the :
Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
Answer:
x = 26.3
Step-by-step explanation:
There are three trigonometric rules that this question will apply to, they are:
Where opp is the length of the side opposite to angle Φ, hyp is the hypotenuse of the triangle and adj is the length of a side adjacent to angle Φ.
In the provided picture, angle Φ has been provided alongside the hypotenuse with the opposite side length needing to be calculated. A trig function that includes all three of these must be used. The only one that does have all three is sin, ergo it is what we will use.
In the current equation form, the subject is incorrect and need to be changed so that it becomes the opposite side.
Plug the known values in:
