Answer:
13) both x and y angles are 30° only,because the exterior angles of a triangle are equal to interior angles
Step-by-step explanation:
the length of third side be less than 15+12=27
third side < 27
12 + third side > 15
third side should be greater than 3
And at last the side should be fall between
3< third side> 27 (greater tha 3, and lesser than 27 the value of third should fall)
