Answer:
150 degrees
Step-by-step explanation:
90+30=120.
Since angle afc is bisected by line bf, that means that the angles formed equal each other. Since the total angle measurement is 180 degrees, we do 180-120=60. 60/2=30. 120+30=150 degrees.

can be simplify as



now comparing 3.6 to 3.46
we can say that
3.6 > 3.46 (√12)
This is essentially 16/3 as a improper fraction. Then multiplied by 4/1 would be 64/3 which is 21.3 or 21 3/10

The figure gets smaller. Think of scale factor of enlargement as a multiple of size. If the SF is 2, you double the size of the object. So if the SF is 1/2, then you halve the size of the object.
