The measure of Arc is 90 degree.
What is Arc?An "arc" is a smooth curve that connects two points in mathematics. In general, an arc is a section of a circle. It is essentially a portion of a circle's circumference.
A circle's arc is defined as a portion or segment of its circumference. A chord of a circle is a straight line that can be created by connecting the two ends of an arc. A semicircular arc is one whose length is exactly half that of a circle.
Since, m(arc EF) = Angle subtended by the arc EF at the center
= 146°
m(arc DE) = 90°
Thus, the measure of arc DE is 90 degree.

78°
Step-by-step explanation:
42+60=102
180-102=78
Answer:
Step-by-step explanation:
first find the final interior angle since we need it to find the exterior
60 + 42 = 102
180 - 102 = 78 degrees
then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees
180 - 78 = 102 degrees
x = 102
you honestly could just take the 2 values you already know and add them and use that lol

The Big Time Band put on a community concert. A total of 1,236 people attended the concert. There were twice as many adults as children who attended the concert. How many adults attended the concert?
Answers
Answer:
412 adults
Step-by-step explanation:
Let the number of adults be x
Let the number of children be y
If a total of 1,236 people attended the concert, then;
x + y = 1236 .....1
If there were twice as many adults as children who attended the concert, then;
y = 2x
Substitute y = 2x into 1
x + 2x = 1236
3x= 1236
x = 1236/3
x = 412
Hence 412 adults attended the concert.
