Here are the calculations for each angle:
e. $\angle E_1$
Step 1: Identify the angle $\angle E_1$ as $\angle AEB$.
Step 2: Apply the Alternate Segment Theorem. The angle between the tangent $GBH$ and the chord $AB$ is $\angle GBA = \angle B_1$. This angle is equal to the angle in the alternate segment, which is $\angle AEB$.
$$ \angle E_1 = \angle AEB = \angle B_1 $$
Step 3: Substitute the given value $\angle B_1 = 68^\circ$.
$$ \angle E_1 = 68^\circ $$
$\boxed
