Page 54 - The circumference of every circle is supposed to' be divided into 360 equal parts, called degrees ; each degree into 60 minutes, and each minute into 60 seconds. Degrees, minutes, and seconds are designated by the characters °, ', ". Thus 23° 14' 35" is read 23 degrees, 14 minutes, and 35 seconds. | 677.169 | 1 |

I tried this out and found a couple ways to solve it. One of those I'll detail here. I have to admit that part of the reason that I wanted to solve this is that the figure in the beginning of the video really bugged me.

State whether the following statements are true or false. Justify your answer. (i) The value of $tan\ A$ is always less than 1. (ii) $sec\ A = \frac{12}{5}$ for some value of angle A. (iii) $cos\ A$ is the abbreviation used for the cosecant of angle A. (iv) $cot\ A$ is the product of cot and A. (v) $sin\ θ = \frac{4}{3... | 677.169 | 1 |
The Pythagoras theorem states that 'in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares on the legs'.
A right-angled triangle is a triangl e in which one angle is a right angle, that is its measure is 90 degrees.
The side opposite to the right angle is called the hypotenuse.
