Please edit the question and attach a picture of the figure so that we can answer more accurately :)
According to the picture, angles 1 and 2 have the same measure because they are corresponding angles. Make equal both expressions for 1 and 2 and find x.

x is 3/2. Replace this value in both expression to find the measure of each angle.

The measure of these angles is 47°
Answer=10%
15+2+3=20
2 of which are blue.
Put it over 100, 20x5=100 so 2x5=10

notice |7| 7 is positive, so we can simply remove the bars and use 7 by itself
