Acute angel
Yes, 69 degrees is less than a right angle. A right angle measures exactly 90 degrees, so any angle less than 90 degrees, such as 69 degrees, is considered acute. In this case, 69 degrees is closer to 0 degrees (a straight angle) than it is to 90 degrees.
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
one angle will be 69 degrees while the other angle will be 111 degrees.
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
An angle that measures 142 degrees is classified as an obtuse angle. In geometry, an obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. It falls between a right angle (90 degrees) and a straight angle (180 degrees).

If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
It is a scalene triangle that would have the given angles.
What is a 79 degree of a third angle of a triangle
one angle will be 69 degrees while the other angle will be 111 degrees.
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
69 degrees
A right angle is an angle of 90 degrees.
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
No such thing as opposite of acute angle. An ACUTE angle is an angle of less than 90 degrees. A RIGHT angle is an angle of 90 degrees only. An OBTUSE angle is an angle between 90 degrees and 180 dehrees. An angle of 180 degrees is a straight line. A REFLEX angle is an angle between 180 degrees and 360 degrees.
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
