Answer 1

Answer:

the value is given A=100 and B=130

so let we find C

Step-by-step explanation:

Let c=x

A+B+C = 180°

100 +130 + x = 180°

230 + x = 180°

x = 230 - 180°

x = 50

Answer 2

Answer:

x=50

Step-by-step explanation:

in angle <A - 100+1 = 180 1=80degrees

IN angle <B 130+2 = 180 2=50degrees

so in triangle all angles equal to 180deg

hence 1 +2+x=180 80+50+x = 180

130+x=180 x=50
