Worked example: Triangle angles (diagram)
We have a right triangle that's split into several smaller right triangles. The angle measures in any triangle always add up to 180 degrees. By using this fact and looking at complementary (adding up to 90 degrees) and supplementary (adding up to 180 degrees) angles, we can find the missing angle measures in the triangles.

Triangle Angle Theorems
mathswithmuza on Instagram: "Trigonometric functions are mathematical relationships that connect the angles of a triangle with the ratios of its sides. The most common ones are sine, cosine, and tangent, which are defined using right triangles. For example, sine measures the ratio of the side opposite an angle to the hypotenuse, while cosine measures the ratio of the adjacent side to the hypotenuse. These functions are not limited to triangles; they are used to describe patterns of waves, oscill
