Answer:
B=45 Degrees
Step-by-step explanation:
You can use law of sines to answer. Law of Sines states that
. That means that
. Multiplying 8 to both sides gives us
. By using inverse of sin, we get
. Plugging that into a calculator gives us b=45 degrees.
Answer:
-4, 1
Step-by-step explanation:
Let x = the amount that Seini earned
Then x + 25 = the amount that Gavin
The amount Gavin earned would also = 425 - x (your directions asked you to have 2 equations.)
Together they earned 425:
x + (x + 25) = 425
2x + 25 = 425
2x = 400
Now divide both sides by 2 to find x.
Use all of this data to satisfy the directions.
Answer:
B
Step-by-step explanation:
The answer is B, -12.
Please give me brainliest.
-12^2 --> -144
-144+144 = 0
Therefore, the answer is B, -12.
