Ответ:
x = 50
Step-by-step explanation:
The sum of all interior angles of a quadrilateral is always 360°.
Step 1: Set up equation
x + 10 + 3x + 2x + x = 360
Step 2: Solve for x
Combine like terms: 7x + 10 = 360Subtract 10 on both sides: 7x = 350Divide both sides by 7: x = 50Ответ:
4 6/25 = 106/25 = 4.24
