Answer:
The angles 4, 5 and 6 are 36, 90 and 54 respectively.
Step-by-step explanation:
First, let's find the total number of parts:
2 + 5 + 3 = 10
The amount of degrees per part is 180 / 10 = 18.
Now, we multiply that factor to the ratio:
[tex]2*18 : 5*18 : 3*18//36:90:54[/tex]
Thus, the angles 4, 5 and 6 are 36, 90 and 54 respectively.
