Answer:

x = 55, upper left angle is 135, down left angle is 55

Explanation:

The shape is a quadrilateral and all of the quadrilaterals angles added together is 360 degrees and that little square at the bottom right of the shape means it's a right angle and a right angle is 90 degrees so:

4x - 85 + 80 + x + 90 = 360

rearrange to make it easier to add like terms

4x + x - 85 + 80 - 90 = 360

add like terms

5x + 85 = 360

subtract 85 from both sides

5x = 275

divide both sides by 5

x = 55

Plug 55 into 4x - 85 to find the angles

4(55) - 85 = 135
