Answer:
460
Step-by-step explanation:
5*46=230 one way but round trip is
230*2=460
Explanation:
First, we need to find the values of the sine and cosine of x knowing the value of tan x and x being in the 3rd quadrant. Since tan x = 5/12, using Pythagorean theorem, we know that

Note that both sine and cosine are negative because x is in the 3rd quadrant.
Recall the addition identities listed below:









Therefore, the expression reduces to



Factor each
60x^4=2*2*3*5*x*x*x*x
45x^5y^5=3*3*5*x*x*x*x*x*y*y*y*y*y
75x^3y=3*5*5*x*x*x*y
common is 3*5*x*x*x=15x^3
gcf=15x^3
Answer:
rectangle are congruent because opposite sides of rectangle are equal. We also know that diagonals of rectangle bisect each other
