Question

One of the exterior angles of a triangle is 100 degree and the interior angles are in the ratio2:3 then all the angles of the triangle are ​

Answer 1

Answer:

Step-by-step explanation:

the exterior angle is 100°

so the rule was applied that , if a side of a triangle is produced the exterior angles so formed is equal to the sum of interior opposite angle

so 2:3

2x+3x=100

5x=100

x= 20

2x= 40

3x=60

third angle found by liner pairs

180=100-z

z =80

first :40

second:60

third:80
