Answer:70 degrees and 150 degrees
Step-by-step explanation: The angles of a quadrilateral add up to 360. So the sum of the two angles is 360 - (55+ 85) = 220.
After that you can model the sum of the angles with an equation:
7x + 15x = 220
22x = 220
x = 10
then you plug in x for each angle 7(10) = 70 and 15(10) = 150
-16w-26+9w=-61
-16w+9w=-61+26
-7w=-35
w=5
10:18 and 15:27 because whenyou mutiply the numerator and denominatorby any number the answer would be equivalent to 5/9
Creo que es la 15 porque si fuera otra pues no lo sé sería 12/56 y ya luego 4/5
