1. The major arc ED has measure 180 degrees since ED is a diameter of the circle. The measure of arc EF is 
, so the measure of arc DF is
The inscribed angle theorem tells us that the central angle subtended by arc DF, 
, has a measure of twice the measure of the inscribed angle DEF (which is the same angle OEF) so
so the measure of arc DF is also 64 degrees. So we have
###
2. Arc FE and angle EOF have the same measure, 56 degrees. By the inscribed angle theorem,
Triangle DEF is isosceles because FD and ED have the same length, so angles EFD and DEF are congruent. Also, the sum of the interior angles of any triangle is 180 degrees. It follows that
Triangle OFE is also isosceles, so angles EFO and FEO are congruent. So we have
Answer: $D - $R
Step-by-step explanation:
Given the following :
Amount Jen had initially = $D
Amount had after purchasing video = $R
Amount she paid for the video =?
Amount she paid for video = ( Initial amount had before purchasing video - amount had after purchasing video)
Hence,
Amount paid for video = $D - $R
If 94 has any other factors other than 1 and itself it is a composite number if it has only 1 and itself then it is prime
