Answer:Area = 492.4 m²
Explanation:The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)
This rule is illustrated in the attached image.
Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees
The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²
Hope this helps :)
So you have 10 gallons of gas
You use 1.625 or 1.63 an hour
You can either do 10/1.625 = 6 hours and 15 mins
You can either do 10/1.63 = 6 hours and 13 mins
6*(4+5)
you do parenthesis first, which equals 9.
9*6 = 54
The answer might be wrong but the answer is either 824 or it could be 24.
It would be D, because if you divide them you would end up with something that looks like this:
x (2x-1)
----------
(2x-1)
Then if you cross out both of the two 2x-1, all that is left is the x.
