Let's use the distance formula to find the distance between the origin and each of the points. We can use this to show that the distances are the same. Remember that the distance formula is:
is one point
is the other point that you are trying the distance to
First, let's find the distance between the points (3, 1) and the origin, (0, 0). We will call this distance 
.
Next, let's find the distance between (1, 3) and the origin, (0, 0). We will call this 
.
We can see that 
, or that the distances are the same. ✔︎
Answer:
9x^3 y^5
Step-by-step explanation:
Since the formula to finding area is (L*W = A), we first have to find the width.
Width: 3x^3 y^5 times 2 = 6x^3 y^5
Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5
We are given all three angles here:
Angle A =68 degrees
Angle B =90 degrees
Angle C =22 degrees.
Now let us calculate :
sin (A) = sin (68) = 0.927
cos (B) = cos (90) = 0
sin (B) = sin (90) =1
cos (C) = cos (22) = 0.927
tan (C) = tan(22) =0.4040
So we can see that sin (A) and cos (C) are both equal to 0.927.
So cos (C) is the correct option.
