Looking at the diagram, Each division is 90 degrees. We can see the 90 degrees symbol there. Therefore,

$17x\text{ + 7 + 9x + 5 = 90}$

$17x\text{ + 9x = 90 - 7 - 5}$
$26x\text{ = 78}$
$x\text{ = 78/26 = 3}$

Also, vertically opposite angles are equal.

Therefore,

$y\text{ = 17x + 7}$

Substituting x = 3 into the above equation,

$y\text{ = (17 }*3)+7=58\text{ degrees}$
