An acute angle
90 - 25 = 65. The answer is 65 degrees.
335 degrees
65 degrees
For ALL triangles drawn in a 2-dimensional plain , the sum of the interior angles if ALWAYS 180 degrees. So for a triangle of 105 + 55 + X = 180 Hence 160 + X = 180 X = 20 The answer !!!! NB For triangles drawn across the surface of a sphere ( the Earth) , 3-dimension, then the sum of the interior angles may be GREATER than 180 degrees.
No. Assuming the first refers to the measure in degrees, it is 60 times as large.
It is: 360/25 = 14.4 degrees

360/25 = 14.4 degrees
Exterior angle of a regular 25-gon = 360/25 = 14.4 degrees. So interior angle = 180-14.4 = 165.6 degrees.
180-120-35 = 25 degrees
25% of 360 degrees is 90 degrees
