Given


Required
The bearing back to the base
The given question is illustrated with the attached image.
To do this, we simply calculate the measure of angle a using:



Take arctan of both sides


One way to carry out this problem is to simply take the value that you already know, which is that 1/5 is 20 % and multiply it by 2 for 2/5 or 2 (1/5ths) and do this for all of them. There is a pattern that occurs for every increase in one out of denominator of 5.
The answer would be 16
11 + (8-3)^2 - 20 = 16
Answer:
the sum of the other two angle is 93
Step-by-step explanation:
180-87=93
