Question

can you solve this please
​

Answer 1

Answer:

x = 60

y = 60

Step-by-step explanation:

by angle sum property

x + y = 57 + 63

x + y = 120

Here x and y are the bisect of angle bce

so

x = y

so

x + y = 120

x + x = 120

2x = 120

x = 60

so

x + y = 120

60 + y = 120

y = 60

Answer 2

Step-by-step explanation:

So First let's find third angle of triangle.

Let the third angle b s.

Sum of angles = 180

57 + 63 + s = 180

120 + s = 180

s = 60 Degrees

y = 63 Degrees (Alternate Angles)

And at last we cane take out x by making equation.

63 + 60 + x = 180

123 + x = 180

x = 180 - 123

x = 57 Degrees

May the answer helps you!!!
