Explanation:
Given:-
m∠3=62°
m∠4=?
An triangle has 3 angles...
We just know that we have ∠3 and ∠4 , so let make 3rd angle ∠2...
(#=Therefore...bcuz I don't have therefore sign in my writing pad )
Therefore....
#∠2+∠3+∠4=180° ......(sum of measures of all angles of a triangle is 180°)
#m∠4-∠2=180°- ∠3
#∠2=180-62
#∠2=112°
#∠=112/2
#m∠4=56
Hope it helps you dear friend....
