Answer:
The vertex angle is 180-(60+75)=45.
k/sin75=900/sin45 so k=900sin75/sin45=1229km approx.
Step-by-step explanation:
What ever solution is left over after solved
About 10 songs because if you add up all ten numbers of all the songs then you divide, then you divide again you will get 10 songs
Answer:
B
Step-by-step explanation:
First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial
. We can now use the quadratic formula to solve.
Remember that the quadratic formula is

Substitute the numbers from the equation into the formula.

Simplify:


Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with
.
Hope this helps!
