Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3

This equation cannot be solved as there is one “x” on each side, which would cancel each other out and leave us with:
-2 = 4
this statement is not true, so there is no solution.
hope this helps. ❤️
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
