That week we did introduction in relations and funtions and how to do them.
a relation is how and equation in a X and Y axis has a pattern that is repeated all the time. function is a relationship between two variables. The first variable determines the value of the.
here is an example of a relation↓↓↓
in this picture there is so pattern in each question that has a repetition. In a graph the lines should connect because it is a continuous variable.
What we did that week was how measurements connected to trigonometry. Measurements has 2 kinds that are commonly used, the Imperial measurement and the SI measurement(Metric). Trigonometry deals with the relations of the sides and angles of triangles and with the relevant functions of any angles.
what their connection is without knowing what measurements you are using (cm,m,mm,ft,in), you cannot solve trigonometry.
how to solve this is finding the missing side. To find the missing side of this triangle, I had to do Pythagoras( a^2+b^2=c^2). I had to add 4.8^2 + 9.3^2=c^2 and the answer is 109.53 squared which is 10.5
