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
Yes
one angle will be 69 degrees while the other angle will be 111 degrees.
An angle of 175 degrees is an obtuse angle
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.
69 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.
Yes
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.
An angle of 175 degrees is an obtuse angle
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.
