Final: The Full Round

Part of the Angles section of Coddy's Geometry journey. Lesson 60 of 62.

Back to the full turn, now with the section’s habits: a silent square, several knowns, one unknown, and this time you write the equation. Marks count, numbers gather, the turn pays.

Challenge

Hard

Four angles share the point: a right angle, 135°, 60° and x°.

$Angles around a point: a right angle, 135 degrees, 60 degrees and x degrees$

Write the equation the figure states. Do not solve it.
