This video is a tutorial on how to solve certain right triangles particularly if we have a two triangle system. The video starts with an example where two right triangles are adjoined to each other and the angle between them is 40 degrees. The length of the blue line is 800. The video then asks what the value of x is. The video then breaks the problem down into two smaller triangles and uses the sine, cosine, and tangent functions to find the values of h1 and h2. The video then adds h1 and h2 to find the value of x. The video then gives two more examples of how to solve right triangles with two triangle systems. The first example is a triangle with angles of 30 and 39 degrees and a base of 200. The second example is a triangle with angles of 25 and 35 degrees and a base of 400. The video concludes with a more challenging example where the distance between two points is 80 and the angles between them are 43 and 35 degrees. The video then uses the tangent function to find the value of x.
Which of the following is not an angle measure in degrees: 35 degrees, 180 degrees, 360 degrees, 90 degrees?
The Pythagorean theorem states that a^2 + b^2 = c^2, for what shape?
Which of the following is not a trigonometric function: sine, cosine, tangent, cotangent?
