The first one in the top is 180 degrees so 8(15) and 8x15=120 so x on the other side is 60.
6.45 + 19.82 = c) 26.27
64.5 + 1.983 = a) 66.483
6.45 - 1.983 = b) 4.467
64.5 - 19.83 = d) 44.67
From the diagram, we can conclude that 5x = 15, 4y = 8, and 2z - 1 = 24.From that, we solve and get x = 3, y = 2, and z = 12.5
Hope this helps!
