WILL MARK YOU BRAINLIEST HURRY IM ON A TIME LIMIT PLZ

L

Step-by-step explanation:

see in the picture, L   is belong to the perpendicular bisector of RS

=> LR = LS (1)

L is belong to the perpendicular bisector of ST

=> LS = LT (2)

from (1)(2) => LS = LT = LR

=> L is equidistant from the points R, S, T

=> L is the center of circle

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

answer: no
