Answer:

Option D is correct

\angle E = 32^{\circ}

Step-by-step explanation:

In the given diagram below DE and EF are tangent to O.

Join the point D and O and O and F as shown below.

It is given that:

\text{arc(DF)} = \angle DOF

⇒148^{\circ} = \angle DOF

or

\angle DOF = 148^{\circ}

A line is tangent to circle if and only if the line is perpendicular to the radius drawn to the point of tangency.

Since, DE and EF are tangent

then:

\angle ODE = \angle OFE = 90^{\circ}

In a quadrilateral EDOF:

Sum of all the angles add up to 360 degree.

\angle FED +\angle ODE + \angle DOF+ \angle OFE = 360^{\circ}

Substitute the given values we have;

\angle FED +90^{\circ}+ 148^{\circ} +90^{\circ} = 360^{\circ}

⇒\angle FED + 328^{\circ} = 360^{\circ}

Subtract 328 degree from both sides we have;

\angle FED = 32^{\circ}

Therefore, the measure of angle E is, 32 degree.
