A 45-45-90 triangle has the hypotenuse of 1. what is the length of one of its legs?
sin theta = opp/hyp sin 45 = opp/1 opp = sin 45 = sqrt(2)/2 ~= 0.7071
What Does OPP in math terms mean?
In mathematics, OPP typically stands for "Opposite." It is commonly used in trigonometry to refer to the side of a right triangle that is opposite to a given angle. The OPP side is the side that is directly across from the angle in question. Understanding the relationship between the OPP side and the other sides of a right triangle is crucial in solving trigonometric problems.
What can help you remember the ratios for cosine and tangent?
A memory trick that I learned for trigonometric values is:Sin: opp/hypCos: adj/hyptan: opp/adjSoh-Cah-Toa
The hypotenuse of a 30 60 90 triangle has length 13 What is the length of the side opposite the 60?
Sin 60 = opp/hyp, in this case opp/13 so opp = 13 sin 60 = 13 x (sqrt 3)/2 = 6.5 x 1.732 = 11.26 (and third side is 6.5)
What are the differences between a parallelogram and a trapezoid?
A parallelogram has 2 pairs of opp sides parallel but a trapezium has only 1 pair of opp sides parallel....a trapezium cannot be a paralellogram but a parallelogram can be a trapezium.
