Step-by-step explanation:
Let the angle be x
so, the angle be 5x and 7x
we know that total sum of a triangle = 180°
According to Ques
5x + 7x + 60 ° = 180°
12x + 60° = 180°
12x = 180° - 60°
12x = 120°
x = 10°
so,
5x = 5× 10° = 50°
7x = 7×10° = 70°
Therefore other two angle is 50° and 70°

Answer:
Angle A=60°
Angle B =50°
Angle C =70°
Step-by-step explanation:
Let angle A =60
angleB=5x
angleC=7x
Sum of all angles of triangle =180
So
angleA+angleB+angleC =180
60 + 5x + 7x =180
60 +12x =180
12x =180 -60=120
12x =120
x =120/12
x=10
Now
angleA=60°
angleB=5x
5*x
5*10=50°
angleC=7x
7*x
7*10=70°
