Answer:
120
Step-by-step explanation:
Here, we want to get the possible value of A
Now, we should understand that the value of an angle in triangle cannot be more than 180
Also, cosine can only be negative in the second and the 3rd quadrant
So,
arc cos (-0.5) = 120 , 300 , 60
But 60 is not correct as it will give a negative value
300 is not correct also as it is more than the angles present in a triangle
Thus, our answer is 120

I think the answer is 2.4 x 10^3
Hope this helped.

Then rearrange the equation to get 10x on the same side as 25.
Keep in mind, once bringing to the other side, your constant and variable will switch to a negative or positive for example,
-10x will become +10x. Another example is +20x will become -20x once brought to the other side.
Continuing on once rearranged, your equation will look like,

Then we have to get rid of the 2 on 2y so you will have to divide both sides by 2.

Dividing both sides by 2, you will get,

The reason why we don't divide and rather keep the 25/2 (25 divded by 2) is because 25 divided by 2 will give an answer with a decimal and that we don't want a decimal in our equation so we just keep it the way it is. If you ever get a decimal, make sure you keep it in its fraction form.
A sailboat travels 3 miles in 1.5 hours. How far does it travel in 2 hours.
= 3 miles / 1.5 hours
= 2 miles per hour
= (2 miles) * (2 hours)
= 4 miles in 2 hours.
So, in conclusion, if a sailboat travels 3 miles in 1.5 hours, it travels 4 miles in 2 hours.
