The sine of one acute angle is equal to the cosine of another when their sum is 90°.
.. (2β +10°) +(3β -25°) = 90°
.. 5β -15° = 90°
.. 5β = 105°
.. β = 21°

Then your equation becomes
.. sin(52°) = cos(38°)

Which set of data has the same mode and median?
AlekseyPX
Median is the middle number and you have to put each set in order like you've done, tick each number off and each side working in:
3,4,-6-,7,8 =6
3,3,-4-,5,5 =4
6,7,-7-,8,9 =7
2,2,-3-,4,6 =3
Mode is the number that shows up the most
3,4,6,7,8= no mode
3,3,4,5,5= 3 and 5
6,7,7,8,9=7
2,2,3,4,6=2

6,7,7,8,9 both have 7 for mode and median
