Let a,b,c be the angles of triangle

Given a+b=80&a-b=20

Add both

(a+b)+(a-b)=80+20

2a=100

a=50

b=80-50=30

c=180-(50+30)=180-80

=100

Angles of the triangle are 100,50&30

Answer:

Step-by-step explanation:

x+y=80

x=y+20

x=80-y

20+y=80-y

2y=60

y=30

x+30=80

x=50

80+z=180

z=100

Angles:

x=50

y=30

z=100
