2. Given an angle and the hypotenuse Apply the law of sines or trigonometry to find the right triangle side lengths: a = c × sin(α) or a = c × cos(β) b = c × sin(β) or b = c × cos(α) 🙋 Refresh your knowledge with Omni's law of sines calculator! 3. Given an...
The sides adjacent to the right angle are referred to as legsaandb, and are also often referred to as the base and height. The calculator uses the term height to represent the altitude of a triangle. The side opposite the right angle is called the hypotenusec. ...
A = ab ÷ 2 × sin(γ) a = side a b = side b γ = angle How to Find Area of a CircleA circle is a round shape with no corners or edges. Each point along a circle is equidistant from the center. It’s important to note that a circle is a two dimensional shape, but it...
Use the given information and a calculator to find to the nearest tenth of a degree if 0 degree less than equal to theta less than equal to 360 degree sin theta =-0.3090 with theta in QIII sin theta =-0.7660 with theta in QIV Let t...

Sine, cosine and tangent, often shortened to sin, cos, and tan in mathematical operations and on calculator keys, are the most basic trigonometric functions. All three are based on the properties of a triangle with a 90-degree angle, also known as a right triangle. By knowing the sides of...
Calculate the cosine of the angle the ladder makes with the ground. It's 1220=0.6 Using a table of cosines (or a scientific calculator), you'll find the angle to be almost exactly 53 degrees. This makes the angle of the ladder against the wall ...
