### Are all complementary angles adjacent?

No, because a complamentary angle just equals 90 degrees. An adjacent angle has a vertex and a common ray the same. If you have two angles that are not touching they cannot be adjacent because they dont have a same ray, but they may have a same vertex. If the two angles add up to 90 degrees they are complimentary and dont have to have anything the same. Hope this helps! If it is confusing…

### What is an adjacent angle?

An adjacent angle is either of two angles having a common side and a common vertex. Adjacent angles are angles that have a common ray coming out of the vertex going between two other rays. Another way of saying this is that adjacent angles are next to one another, side by side or adjacent. ( Hence the name) It is an angle next to another one in a polygon. Adjacent angle means oppisite of each…

### What are facts about right triangles?

The ratio of the length of the side opposite a given angle to the hypotenuse is the sine of that angle. The ratio of the length of the side adjacent to a given angle to the hypotenuse is the cosine of that angle. The ratio of the length of the side opposite a given angle to the side adjacent to that angle is the tangent of that angle.

### Can a straight angle be an adjacent angle?

It meets all definitions I can find, and it would seem that a straight angle can be adjacent. Definition: (1) Two angles that share a common side and a common vertex, but do not overlap. (2) An adjacent angle is either of two angles having a common side and a common vertex. Adjacent angles are angles that have a common ray coming out of the vertex going between two other rays. Another way of saying…

### What to do when you have the hypotenuse and angle?

For trigonometry if you have the value of the hypotenuse and the angle, it depends what side you are trying to find. If you are looking for the side across from the angle, the formula is sine(angle)=opposite side divided by hypotenuse. If you are looking for the side adjacent to the angle, the formula is cosine(angle)=adjacent side divided by hypotenuse. Hope this helps!
