Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
Since this is a 45-45-90 triangle, n = 9 and m = x
Answer:
total - given, 360 -139 = 221
We need to find the other base also in order for us to find out what the area of this is.
4cm, as if two of the sides add up to be the same length as the first side then the triangle would be a straight line.
