Question

Help please! there’s a hint if you flip the screen

Answer 1

Explanation:

We can see that:-

`x - 10`

and

`x - 11`

are in Opposite manner , so, we will add three angles together. These are as follows:-

`(x - 10) + (x - 11) + (3x + 6) = 180 ^ \circ`

You, know why I did 180°, that is because these all angles form a straight line and we know that straight lines have angle of 180°.

Continuing with the equation:-

`x - 10 + x - 11 + 3x + 6 = 180`

`5x - 21 + 6 = 180`

`5 x - 15 = 180`

`5x = 180 - 15`

`5x = 165`

`x = 33 ^ \circ`

Now, in order to find y we need the value of 3x+6. And when we will find it, it will be Vertically Opposite hence the answer will directly be placed to find y.

`3(33) + 6`

`= 99 + 6`

`y = 105 ^ \circ`
