90° - 12° = 78°
s/7m = tan78°
s = 7m tan78° ≈ 32.9 m
Yes, there is such thing as a right-angled triangle. The measure of the adjacent and opposite form together to create a 90 degree angle. That means that the measure of the hypotenuse and adjacent must be 45 degrees and the hypotenuse and opposite measures to 45 degrees.
It is called the hypotenuse. The adjacent side is beneath it and the opposite side opposite it.
First: there can only be one hypotenuse in a right angled triangle and it is always OPPOSITE the right angle, NEVER adjacent.
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
When considering an angle in a right angled triangle, the adjacent is the short side next to the angle and the hypotenuse is the long one (which will be opposite the right angle)
They may be defined as the ratios of the lengths of sides of a right angled triangle, relative to either of the other angles.sine = opposite/hypotenusecosine = adjacent/hypotenusetangent = opposite/adjacentcosecant = hypotenuse/oppositesecant = hypotenuse/adjacentcotangent = adjacent/opposite.
If the pole is on level ground then you have the outline of a right angled triangle with an opposite side of 3 feet and an adjacent angle of 30 degrees. To find the length of the adjacent side (which in effect is the shadow of the pole) use the tangent ratio: tangent = opposite/adjacent which can be rearranged to: adjacent = opposite/tangent adjacent = 3/tangent 30o = 5.196152423 feet Therefore the shadow cast by the pole is 5.2 feet corrected to one decimal place.
Its a way of remembering the three trigonometrical ratios of a right angled triangle: soh means: sine = opposite/hypotenuse cah means: cosine = adjacent/hypotenuse toa means: tangent = opposite/adjacent
Suppose ABC is a triangle. There is nothing in the question that requires the triangle to be right angled. Suppose AB is the side opposite to angle C and BC is a side adjacent to angle C. Then AB/BC = sin(C)/sin(A)
For a right angle triangle the trigonometrical ration is: tangent = opposite/adjacent

An acute-angled triangle is a triangle in which all the interior angles are between 1 and 89 degrees.
