The value of k is 400 points.
If the player fails to complete 100 tasks, then they lost 200 points. At the end of the game, they had 200 points.
We can write and solve the following equation to determine where they started.
x - 200 = 200
x = 400
-4 is what you put on both sides Bc it’s half of b
Use the formula a^2+b^2=c^ which is 7.21
COS A=0.8
Step-by-step explanation:
2^6+8^2
100
sqrt(100)=10
8/10
0.8
Answer:
6.2 units.
Step-by-step explanation:
We are given two angles and an opposite corresponding side. To solve for an unknown side, we can use the law of sines.

Cross multiplying and solving will get you this:

Which can simplify to:

Which putting into a calculator gets you:

So the line PR is 6.2 units long.
