I don’t understand how you do f and g

144 degrees

27 degrees

Explanation:

f) So angle EBD is angle 5, which is 36 degrees. Angle DBC is angle 1 and is 108 degrees. We need to find angle EBC or 5 + 1.

So we know that EBC is angle 5 + 1, we can do angle 5 plus angle 1 or:

36 degrees + 108 degrees = 144 degrees.

Angle EBC is 144 degrees.

g) So we know angle EBF or angle 4 + 3 is 117 degrees. We need to find angle ABE or angle 4. We know that angle 3 is 90 degrees because of BF is perpendicular to AC. So now we can find angle ABE or 4:

117 degrees minus 90 degrees = 27 degrees

Angle ABE is 27 degrees.
