1st angle = 30 degrees 2nd angle = 60 degrees
120 degrees = 2X60....supplemental total = 180
one angle will be 69 degrees while the other angle will be 111 degrees.
108 degrees, 54 degrees and what ever it take to make 180. 18 degrees.
The angles are 40, 80 and 60 degrees.
The complement is 60 degrees.
116 degrees
1st angle = 30 degrees 2nd angle = 60 degrees
60 degrees and 120 degrees
90 degrees
23 degrees and 67 degrees
120 degrees = 2X60....supplemental total = 180
The 3 interior angles are 90 degrees, 45 degrees and 45 degrees
16.36* It is, in fact, twice that: 32.7272.. degrees.
The measure of the intercepted arc is twice the measure of the tangent chord's angle. Therefore, if the measure of the tangent chord is 74 degrees, the measure of the intercepted arc would be 2 × 74 degrees, which equals 148 degrees.
the answer is twice. the angle of rotation is twice the measure
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
