Answer:

Step-by-step explanation:
Solving trigonometric equations.
We are given a condition and we must find all angles who meet it in the provided interval. Our equation is

Solving for 5x:


The values for x will be


To find all the solutions, we'll give n values of 0, 1, 2,... until x stops belonging to the interval 
For n=0


For n=1


For n=2


For n=3


For n=4


For n=5 we would find values such as


which don't lie in the interval 
The whole set of results is

Take 36 and add it to 60 it gives you 96 then divide it by 2 and the answer is 48
Answer:
Line 3 is incorrect; we don't know anything about the lengths of HG, FG, HE, and EF, so this line is not valid based on the given information.
Step-by-step explanation:
In the Noah's poof of the construction, segment EG would divide angle FGH into two equal parts, which makes line 2 to be valid. i.e <EGH ≅ <EGF. And it can also be observed that line 4 is a valid theorem in proving the congruent nature of triangles.
But line 3 is not valid because of the condition of the statement. Furthermore, segments FG, EG, HG, HE and FE may not be congruent. Thus, the condition of the statement in line 3 is incorrect.
