Question

The sum of two angles of a triangle is 120ð and their difference is 20ð . find all the three angles

Answer 1

here you go ☆☆

▪let third angle = x

sum of all angles of triangle = 180°

▪120 + x = 180
▪x = 180-120
▪ 60°

▪let first angle be a and second angle be b
▪a+b= 120--------
▪a-b=20--------ii
▪subtracting ii from I
▪ a+b= 120
▪a-b=20
▪2a= 100

▪a= 100/2
▪a= 50

therefore
▪ b = 120-50
▪ 70


three angle are:-
60°, 50° ,70°
