What do you do in trigonometry when you are only given the opposite and adjacent sides?

That depends what you're asked for.
If you're asked for the tangent of the angle, divide (opposite)/(adjacent) .
If you're asked for the hypotenuse of the triangle, it's sqrt( opposite2 + adjacent2 ) .
If you're asked for the cosine of the angle, it's (adjacent)/(hypotenuse) .
If you're asked for the other acute angle, it's the angle whose tangent is (adjacent)/(opposite) .
If you're not asked for anything, then get your jacket, chew some gum, and go home.

How do you find an angle of a right triangle when 3 sides are given?
you need a calculator to do Sin-1 Opposite/hypotenuse OR Cos-1 Adjacent/Hypotenuse OR Tan-1 Opposite/Adjacent
What is a non adjacent sides of a quadrilateral?
opposite sides
What is the definition of opposite sides in geometry?
Adjacent
What is the shape Opposite sides are equal adjacent lines are not?
polygon
What are difference between the sides of a right angle?
The side of a triangle that is opposite to 90 degree angle is called hypotenuse. The side that is opposite to the given angle (The angle that is under calculations) is called opposite. The side that is adjacent with the given angle is called base.
What are the types of sides in trigonometry?
They are: opposite, adjacent and hypotenuse sides for a right angle triangle
Which is the opposite and adjacent sides in a triangle?
Each triangle has three sides and three vertices. The opposite side of a triangle is the side that is not adjacent to the specified vertex. The other two sides are adjacent sides to the specified vertex. Circular definition? Yes - Here is the formal definition... Given a triangle with vertices A, B, and C, the side AB is adjacent to the angles ABC and BAC, and it is opposite to the angle ACB.
What are the sides of a triangle called?
Given the reference perspective of a specific angle the sides are are the adjacent sides and the opposite side If we have a right triangle the longest side (opposite the right angle) is the hypotenuse.
What is the name for the sides of a right triangle that are adjacent to the right angle?
Opposite and adjacent sides.
How do you find an angle of a right triangle when 3 sides are given?
you need a calculator to do Sin-1 Opposite/hypotenuse OR Cos-1 Adjacent/Hypotenuse OR Tan-1 Opposite/Adjacent
What is a non adjacent sides of a quadrilateral?
opposite sides
How do you determine which is the adjacent side of a right triangle?
There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).
What is the definition of opposite sides in geometry?
Adjacent
Which quadilaterals have opposite sides parallel and adjacent sides perpendicular?
rhombus
Are all sides perpendicular in a rectangle?
Adjacent sides are perpendicular. Opposite sides are parallel.
How many adjacent sides does a square have?
Each side of the square has two sides adjacent to it. Ex. if you just look at only one side, the sides next to it are the adjacent sides, not the one opposite of it.
If the opposite a 45 angle in a right triangle equal 12.5 meters how long is the side adjacent the angele?
The length of the line adjacent to angle 45 degrees will also be 12.5 meters because in effect the given triangle is that of half a square with 4 equals sides of 12.5 meters or alternatively using trigonometry 12.5*tangent(45) = 12.5 meters
