I d k the answer but thanks for the points! LOL
90. Add the zero in front of the 9.
63degrees
Step-by-step explanation:
there are multiple ways to do this
for one, angle a = angle e (corresponding angles)
angle f + angle e = 180 degrees (angles on a straight line)
angle f = 180 degrees - angle e where angle e = angle a = 117degrees
so angle f = 63 degrees.
2/3 is exactly the same as 8/12
