Answer:
- The angles in a quadrilateral sum up to 360°.
- The angles given here in the ratio form are : 4x, 5x, 10x and 11x.
Hence, 4x + 5x + 10x + 11x = 360
- ⇒ 30x = 360
- ⇒ x = 360/30
- ⇒ x = 12
Hence, the angles = ?
- ⇒ 4x = 4(12) = 48°
- ⇒ 5x = 5(12) = 60°
- ⇒ 10x = 10(12) = 120°
- ⇒ 11x = 11(12) = 132°
- Therefore, the angles are : 48°, 60°, 120° and 132°.

Important :
- A quadrilateral is a four sided shaped.
- It has 4 vertices.
- Sum of interior angles : 360°
- Perimeter is the sum of all four sides.
- Area = ½×diagonal×(sum of perpendicular heights)

ʜᴇʀᴇ ᴡᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ,
Now we have to find the value of "X"
so,
now on adding these numbers,
we get,
so on putting value of X in all angles :
we get,
hence,
angles are = 48°
=60°
= 120°
=132°
