Answer 1

this is an isosceles triangle with 2 sides equal
The base angles are also equal

Answer 2

Well, those two sides are same, so you know what one angle is. Then other angles are 180 - 110.5, then divide that by 2.

Answer 3

now the 3 angles of a triangle add up to 180 degrees
so angle x = (180 - 110.5) / 2

Answer 4

34.75

Answer 5

yes
