All of my friends are disagreeing be the tie breaker and explain

A.) it's unlikely to rain tomorrow

I choose this answer because it's still likely to rain the next day because it usually goes up the higher it is

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
