Answer:

❤❤ It's a linear pair

So , X - 10° + 4X - 20° = 180°

5X - 30° = 180°

5X = 180° + 30°

X = 210°/5

X = 42° --> Ans. ❤❤

Answer 2

Answer:

x- 10 +4x -20= 180 sum of interior angle of triangle.

5x- 30= 180 .

5x= 180+30

5x= 210 .

x= 210/5

x= 42.

..

according to question

42-10= 32°

second angle

4*42-20.

148

...

hence 148+32 is equal to 180..////

hence verified lhs= rhs
