63 degrees because 180 -39 -78 = 63
The TWO (not one) missing angles are 102 and 70
yes it is
An angle of 78 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
78 is an acute angle as it is less than 90, 144 is an obtuse angles as it is between 90 and 180
63 degrees because 180 -39 -78 = 63
An angle of 78 degrees is an acute angle
An angle whose measure is 78 degrees!
78 degrees is an acute angle
The TWO (not one) missing angles are 102 and 70
180 - 78 = 102 and 180 - 123 = 57
90-78 = 12 degrees
Using the ambiguous rule in trigonometry its other angles are 35 degrees and 115.55 degrees with a 3rd side of 143.14cm or its other angles are 145 degrees and 5.55 degrees with a 3rd side of 15.35cm
90 degrees and 78 degrees since one of the angles must be 90 degrees. We have 90+32=122 which is the second angle. Now the sum of the angles is 180 so 180-122=78 which is the third angle.
yes it is
Assuming that in a parallelogram, angle A = 78 degrees angle B = 3y degrees and that angles A and B are adjacent interior angles of the parallelogram. 78 + 3y = 180 so 3y = 102 and so y = 102/3 = 34 degrees.
An acute angle.
