Question

if the ratio of the angels of a triangle be 4:5:9, find the angles. ​

Answer 1

Answer:

angle 1= 4×10= 40°

angle 2= 5×10= 50°

angle 3= 9×10= 90°

Answer 2

Answer:

/_1=40

/_2=50

/_3=90

Step-by-step explanation:

let the number be x,therefore 4=4x,5=5x,9=9x.

4x+5x+9x=180° (sum of all interior angles of triangle =180°)

18x=180°

x=180/18

x=10

4x=4×x=4×10=40°

5x=5×x=5×10=50°

9x=9×x=9×10=90°
