Answer:
The possible values of x are 90°, 30° and 150°.
Step-by-step explanation:
Given that,
sin(2x) = cos(x) where 0° ≤ x < 180°
We know that, sin(2x) = 2 sinx cosx
2 sinx cosx = cosx
Subtract cosx on both sides
2 sinx cosx - cosx = 0
cosx (2sinx-1)=0
It means, cosx = 0 and (2sin x -1 ) = 0
cos x = cos0 and sinx = 1/2
x = 90° and x = 30°, 150°
Hence, the possible values of x are 90°, 30° and 150°.

Step-by-step explanation:
How to round off to the nearest degree
lets pick this number: 3,266.528
first let round to the nearest whole number by thousand
lets remove the .528 because we don’t need it
3,266
4000-3266 is 734
3,266 minus 3000 is 266
so rounded to the nearest thousand in the whole number is 3,000
or let’s say hundredths
3266.528
0.3- 0.28 is 0.3
0.28 - 0.2 is 0.8
so rounded to the nearest hundredth is 3,266.53
hope this helps :)
