hey mate here is your answer....
let the angles be 4x,5x,9x.
now ,
4x+5x+9x=180(ASP)
=18x=180
x= 10
so , 4×10=40
5× 10= 50
9× 10=90
so it's is a scalene triangle ,as the angles are not equal.
##hope it helps . mark it as brainliest.##

deadpool92:
brainliest
It is a right angled triangle because it makes 90 degree angle...
If I amn't wrong
no ur also correct
ur welcome n tq @deadpool
how to mark brainliest
but, I think it is a scalene right angle triangle
no u already marked brainliest to wwwwkushi
If I am not wrong

Answer:
The three angles of the triangle are 40, 50 and 90
The given triangle is a right-angled triangle
Step-by-step explanation:
Given,
The angles of a triangle are in the ratio 4:5:9
To find,
The angles of the triangle and the type of the triangle
Solution:
Recall the concept
Sum of three angles of a triangle = 180°
Since the angles of the triangle are in the ratio 4:5:9
Then the angles are 4x, 5x and 9x
Since the sum of three angles of a triangle is 180°, we have
4x+5x+9x = 180
18x = 180
x = 10
Hence the three angles of the triangle are 40, 50 and 90
Since one angle of the triangle is 90°, the given triangle is a right-angled triangle
