HELP ASAP THIS IS GEOMETRY

tekilochka [14]

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,

$(x + 7) = 55$

$x = 55 - 7$

$x = 48$

$y = 180 - (55 + 55)$

$y = 180- 110$

$y = 70$
