Answer:
The answer is 7 1/2 or 15/2 or 7.5 (all the same just in mixed fraction and decimal form)
Step-by-step explanation:
Answer:
x=3.5
Step-by-step explanation:
12x=4(x+2)+20
multiply the parentheses by 4
12x = 4x+8 +20
add 20 to 8
12x = 4x +28
subtract 4x on both sides
8x = 28
divide both sides by 8
x=3.5
The probability of a coin landing on heads is a 50 percent chance. Because there are only two sides. So there is a 1 out of 2 chance it will land on heads. And 1/2 is equal to 50 percent.
We know that the law of sines states that:
For simplicity, let:
In triangle A1BC this leads to:
Therefore:
Now, triangle A2BC is isosceles which means that both the base angles are equal, since angle CA1B and A2A1B are supplementary we have:
What’s is this I don’t know
