Answer 1

Answer:

angle

A=50

B=50

C=80

Step-by-step explanation:

x+10+x-20+x-20=180

3x-30=180

3x=210

X=70

Answer 2

Answer:

80

50 degree.

50

Step-by-step explanation:

we know,

A + B + C = 180 degree. (by angle sum property of

a triangle )

so,

x-20 + x-20 +x+10 = 180

3x - 40 + 10 = 180

3x -30 = 180

3x = 180+ 30

x = 210÷3

x = 70

Now, putting value of x

angle A = 70 - 20 = 50

angle B = 70 - 20 = 50

angle C = 70 + 10 = 80

itz the answer,

it'll help.
