Step-by-step explanation:
to send out something, for example, a smell, a sound, smoke, heat or light
Step-by-step explanation:
we know that the sum of all angles in a triangle is 180 degree , then
x+(x+10)+(x+20) =180
3x +30 =180
3x = 180-30
3x = 150
x=150/3
x= 50
the value of angles:-
x= 50°
x+10 =(50+10)=60
(x+20) =(50+20)=70 , answer....
