Answer 1

Given:

Given that the measure of arc DF is 162°

We need to determine the measure of ∠E

Measure of ∠E:

The measure of ∠E can be determined using the inscribed angle theorem.

Thus, by inscribed angle theorem, we have;

`\angle E=(1)/(2)(m \widehat{DF})`

Substituting
`m \widehat{DF}=162^(\circ)`, we get;

`\angle E=(1)/(2)(162^(\circ))`

Dividing, we get;

`\angle E=81^(\circ)`

Thus, the measure of ∠E is 81°
