Answer:
184
Step-by-step explanation:
1/2 times x = 92
so 1/2 means half so what we do is add 92 to 92 so its 184
We can use following formula

Now, we need to find sin(2A).

Because, the angle A is in the 1st quadrant, and cos(2A) is negative, that means that the angle 2A is in the 2nd quadrant and sin(2A) is a positive number,so sin(2A) = 4/5.
sin(2A) = 4/5
cos(2A) = -3/5
