Question

Help me, please answer this question

Answer 1

`x = 9`

`y = 17`

Explanation:

This is a cyclic quadralterial so opposite angles are supplementary.

The x variables add up to 180 so

`11x + 8 + 8x + 1 = 180`

`19x + 9 = 180`

`19x = 171`

`x = 9`

The y variables add up to 180.

`6y - 4 + 5y - 3 = 180`

`11y - 7 = 180`

`11y = 187`

`y = 17`
