Answer 1

Answer:

a= 95°

Step-by-step explanation:

solution:

   (3x-10)° + (2x+15)° = 180° (∵ sum of  exterior angle is 180)

or, 3x + 2x - 10 + 15 = 180°

or, 5x + 5= 180°

or, 5x = 180° - 5

or, x = 175°/5

or, x = 35°

now pitting value of x,

   ( 3x- 10)°

= (3× 35 - 10)°

=( 105- 10)°

= 95°

∴ a= 95° (∵ vertically opposite angle)

Answer 2

Bro, the value of = (3x - 10)( It is opposite angle)
> Opposite angles are always equal to each other.
(3x- 10). . ANSWER.
