Is 69 degrees less than a right angle?
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.
What is the measure of the base angle of an isosceles triangle if the measure of the vertex angle is 42 degrees and the two congruent sides each measure 21 units?
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
Two angles are supplementary their sum is 180 One angle is 27 less than twice the other Find the measure of each angle?
one angle will be 69 degrees while the other angle will be 111 degrees.
If an angle is obtuse then it has a measure of 120 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.
What is a angle that is 142 degree angle?
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).
