Answer:
x=48
y=70
step by step explanation:
In the question,
Since the triangle two sides of the traingle is equal, it is an isosceles triangle.
For an isosceles triangle, angles opposite to equal sides are equal,
Hence,
[tex](x + 7) = 55[/tex]
[tex]x = 55 - 7[/tex]
[tex]x = 48[/tex]
[tex]y = 180 - (55 + 55)[/tex]
[tex]y = 180- 110[/tex]
[tex]y = 70[/tex]
