Question

Angle C and angle E are supplementary.
What is the measure of angle E?
Trapezoid CDEF. Angle C is labeled 105 degrees.

Angle E is
degrees.

Answer 1

To find the measure of angle E, we can use the fact that supplementary angles add up to 180 degrees. Since angle C measures 105 degrees, we can calculate angle E as follows:

\[
\text{Angle E} = 180^\circ - \text{Angle C}
\]
\[
\text{Angle E} = 180^\circ - 105^\circ
\]
\[
\text{Angle E} = 75^\circ
\]

So, the measure of angle E is 75 degrees.
