90-78 = 12 degrees
It is an acute angle because it's greater than 0 but less than 90 degrees
These two angles total 180o therefore they are each others supplements.
The answer will depend on what a and x are and how they relate to one another. Since you have not provided this information, it is not possible to answer the question.
Suppose the angle is x then its supplement is 180 - x so 180 - x = x - 78 that is, 258 = 2x or x = 258/2 = 129 <><><><><> Angle + Supplement = 180 Angle = Supplement + 78 Solve for the system of equations... Angle + Supplement = 180 Angle - Supplement = 78 ------------------------------------- 2 Angle = 258 Angle = 129 Supplement = 51
An angle of 78 degrees is an acute angle
78 degrees is an acute angle
90-78 = 12 degrees
An angle of 78 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
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
78
