Answer 2

Answer:

so here =. ( 3X + 20 ) + ( 2X - 40 )

= ( 3X + 2X ) + (-40 + 20 )

= 5X + (-20)

so here we need to find the value of x so

as it is a straight angle triangle the sum will be total 180°

so

= 5X + (-20) = 180°

= 5X = 180° - (-20)

= 5X = 200°

= X = 200° / 5

= X = 40°

so here the value of X is 40°
