We know that the sum of all angle measures in a trapezoid is 360* (* means degrees)
Therefore we can construct the equation
(X+28)+(x)+(4x-14)+(4x-14)= 360
Now add like terms
10x = 360
And divide by the coefficient of X (aka 10)
X= 36
To work out 7% of 600, this is what you do
7/100 x 600
this will give you your answer
7% of 600 = 42
The answer for 13 would be 4x-6x=2x
