Answer:
As there are 2 equations and two unknowns there is 1 solution
Answer:
Step-by-step explanation:
Given the equation:
To find:
The solutions of given equation in the range [0, 2) i.e. 0 can be in the answer but can not be there in the answer.
Solution:
Taking common, we get:
The solutions can be given as:
OR
Let us solve both the equations one by one:
First equation:
Second equation:
Therefore, the answers as a comma separated list are:
your almost right check once and you wil get especially alternate angles
