Given:
- Trapezium ABCD
- AB || DC
- ∠A : ∠B = 4:5
- ∠B : ∠C = 3:2

To find:
- The angles of the trapezium

Solution:
Let's assume ∠A = 4x, ∠B = 5x, and ∠C = 3y.

Using the angle sum property of a trapezium:
∠A + ∠B + ∠C + ∠D = 360°

Substituting the given values:
4x + 5x + 3y + ∠D = 360°
9x + 3y + ∠D = 360°

Since AB || DC, ∠D is equal to ∠A.
∠D = 4x

Substituting this value in the equation:
9x + 3y + 4x = 360°
13x + 3y = 360°

Using the given ratio:
∠B : ∠C = 3:2
5x : 3y = 3:2
(5/3)x = (3/2)y
10x = 9y

Now we have two equations:
13x + 3y = 360°
10x = 9y

Solving these equations:
Multiplying the second equation by 13/9 to match the coefficients of x:
(13/9)(10x) = (13/9)(9y)
130x/9 = 13y
130x = 117y

Now we have two equations:
130x = 117y
13x + 3y = 360°

Substituting the value of y from the first equation into the second equation:
13x + 3(130x/117) = 360°
13x + 390x/117 = 360°
(13x * 117 + 390x)/117 = 360°
(13x + 390x)/9 = 360°
403x/9 = 360°

Simplifying the equation:
403x = 9 * 360°
403x = 3240°
x = 3240° / 403
x = 8°

Substituting the value of x in the first equation:
13x + 3y = 360°
13 * 8° + 3y = 360°
104° + 3y = 360°
3y = 360° - 104°
3y = 256°
y = 256° / 3
y = 85⅓°

Calculating the angles:
∠A = 4x = 4 * 8° = 32°
∠B = 5x = 5 * 8° = 40°
∠C = 3y = 3 * 85⅓° ≈ 256°
∠D = ∠A = 32°

Answer:
The angles of the trapezium
