Question

if two angles of a triangle are greater than the smallest angle by 10 degree and 20 degree then find the then find the angles? ​

Answer 1

Step-by-step explanation:

take smallest angle as X

then all the angles = x,x+10,x+20

by angle sum property

x+x+x+10+20=180

3x = 150

X = 50 degrees

therefore all the angles :- 50,60,and 70 degrees

Answer 2

Let the angle is x

first angle is x

second is x+10

third is x+20

x+x+10+x+20=180(angle sum property)

3x=180-30

3x=150

x=150/3

x=50

first =50,second=60,third=70
