Question

Find the values of x and y

Answer 1

`\boxed{x = 45} \:a nd \: \boxed{y = 90}.`

Explanation:

`let \: the \: unknown \: be : \: z \\ then : \\ 180 - 135 = z \\ z = 45. \\ but \: 180 - z = 135 \\ x + y= 135 . \\ but \: since \: both \: side \: are \: equal......then \\ \: both \: bases \: should \: be \: equal \to \\ \boxed{x = z = 45}. \\ 45 + y = 135 \\ y = 135 - 45 \\ \boxed{y = 90}.`
