Question

please answer me friends please I request​

Answer 1

Step-by-step explanation:

8

y + 50° = 180

therefore, y = 180-50,

therefore, y = 130°

and I cannot find x in the given figure

9

let the one angle which is 80 is A

and other angles are B and C

and A+B+C = 180°

80+2B = 180°

2B = 100

B = 100/2

B = 50

also, B = C

Therefore C = 50°

Answer 2

Answer:

9 sum of angles in a triangle are 180. since one angle is 80 and other two are equal each will be 50 (80+50+50=180)
