Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
Answer:
25
Step-by-step explanation:
We can calculate for a using sine rule.
For angle A,
A + 27° + 82° = 180 ( sum of angles in a triangle).
A + 109 = 180
A = 180 - 109 = 71°
Therefore,
A = 71°
calculating for side a
