this is what i have: X= 6+(90-X)+2(90-X) and i got 42 degrees?
The sum of two complementary angles is 90.E.g. 30 degrees and 60 degrees are each others complementary angles.The sum of two supplementary angles is 180.E.g. 105 and 75 are each others supplementary angles.Supplementary angles are those whose angles add up to 180 degrees. Complementary angles are those whose angles add up to 90 degrees.
In geometry, the term "similar" refers to figures that have the same shape but potentially different sizes (length, width, height). Strictly speaking angles don't have "size" so they would not be "similar". On the other hand if we interpret the intent to be to ask about congruent angles in similar figures the corresponding angles (i.e. angles that occupy the same relative position at each intersection where a straight line crosses two others) will also be congruent. If angles are similar in that they have approximately (but not necessarily exactly) the same measure, then their corresponding angles will also be approximately the same as each other. Stated another way: If angles A and B are very close in measure, and angle C is the corresponding angle of angle A and angle D is the corresponding angle of angle B, then angles C and D will be close in measure within bounds that can be predicted based on the difference in measure between angles A and B.
In Euclidean geometry a right angle triangle has two acute angles. All others have three.
An irregular octagon is one in which one of the sides is not the same length as the others or one of the angles is different from the rest.

10 degrees.
It's larger than some, smaller than others.
Bsically...Obtuse- more than 90Right- 90Acute- less than 90Reflex-more than 180I thinkAn angle of 90° (π/2 radians, or one-quarter of the full circle) is called a right angle.Two lines that form a right angle are said to be perpendicular or orthogonal. Angles that are not right angles or a multiple of a right angle are called oblique angles.Angles smaller than a right angle (less than 90°) are called acute angles ("acute" meaning "sharp").Angles larger than a right angle and smaller than two right angles (between 90° and 180°) are called obtuse angles("obtuse" meaning "blunt").Angles equal to two right angles (180°) are called straight angles.Angles larger than two right angles but less than a full circle (between 180° and 360°) are called reflex angles.Angles that have the same measure (i.e. the same magnitude) are sometimes said to be congruent, though the diagrams that represent them need not be congruent, so others (including Euclid) prefer to say that they are equal in size, or just "equal".An angle of 90° (π/2 radians, or one-quarter of the full circle) is called a right angle.Two lines that form a right angle are said to be perpendicular or orthogonal.

These angles are equal in size.Angles that share a common vertex and edge but do not share any interior points are called adjacent angles.Two angles that sum to one right angle (90°) are called complementary angles.

It has 5 sides It has 5 angles The sum of the interior angles is 540° All angles are not the same measure The sides may, or may not, all be the same length. It will not have line symmetry of 5 It has no rotational symmetry (called rotational symmetry of 1 when I was at school).
One and the two others are acute angles
Combining in such a way as to enhance or emphasize each others qualities.
Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°
Yes, a regular hexagon has ALL sides the same length and ALL angles equal. If you flatten it somewhat (like the profile of a lens) then the sides may still have the same length but some angles will be larger than others if opposite angles are the same than there will be symmetry. (there are many other options to retain symmetry in a hexagon this is but one)
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
