You will use the functions soh cah toa. you know that angle b is 90 so the other 2 angles have to add up to 90°. with the Pythagorean theorem we can get that cb is 12 feet. so we now have all side lengths and 1 angle. you can pick out that 53° will be your final answer after doing the basic functions!
522km / 36= 14.5km PER litre
14.5 x 14= 203
If the height is 6ft then the base is 13ft.
78/6=13
Hope this helps.
Let the two integers be x and x + 1, then
x + x + 1 = 113
2x + 1 = 113
