Answer 1

Answer:

90°,50°and 40°

Step-by-step explanation :

Let the ratio of angles be 9x,5xand 4x

ATQ

9x+5x+4x=180 (sum of all angles in

18x=180 triangle =180)

X=180/18

X=10

The angles =9×10=90°

5×10=50°

4×10=40°

Hope it helps....

Answer 2

90 degree,40 degrees ,50degrees

Step-by-step explanation:

we know ,

sum of angles of a triangle is 180 degree

so,

let the ratio of the angles of the triangle be 9x:5x:4x

**this means each angle is 9x degree , 5x degree ,4x degree

so, accordingly to what we know that sum of angles of a triangle is 180 degree so,

ATQ

9x +5x+4x =180 degree

13x + 5x = 180 degrees

18x=180 degree

x= 10 degree

so each angle is 9x,4x ,5x and we have found the value of x so measures of each angle is.

9x=9*10=90 degree

5x=5*10= 50 degree

4x =4*10=40 degree
