It is 12 degrees because 78+12 = 90 degrees
Yes, as for example 78 degrees and 102 degrees would form a supplementary angle of 180 degrees.
63 degrees because 180 -39 -78 = 63
First of all its adjacent and an adjacent angle is and angle that is less than 90 degrees......... :)ex. (78 degrees)
78 degrees I believe.
An angle of 78 degrees is an acute angle
An angle whose measure is 78 degrees!
78 degrees is an acute angle
90-78 = 12 degrees
the measurement of a reflex angle is between 180 and 360 degrees, or between pi and 2pi in radians.
An angle of 78 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
90-78= 12 degrees
An acute angle.
12 degrees
It is 12 degrees because 78+12 = 90 degrees
Yes, as for example 78 degrees and 102 degrees would form a supplementary angle of 180 degrees.
(90 - 78)/2 ie 6o
