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
wwwkhushigarima64: It is a right angled triangle because it makes 90 degree angle...
wwwkhushigarima64: If I amn't wrong
blessy96: no ur also correct
blessy96: ur welcome n tq @deadpool
deadpool92: how to mark brainliest
deadpool92: but, I think it is a scalene right angle triangle
blessy96: no u already marked brainliest to wwwwkushi
deadpool92: If I am not wrong
blessy96: may be

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
