Answer 1

Answer:

Hello mate ✌️.

Step-by-step explanation:

x-y=30 →equation 1

x+y+40 = 180 (since sum of angles of a triangle = 180)

x+y=140 →equation 2  (variables on one side,constants on one side)

equation 1 → x-y=30

equation 2 → x+y=140

                  ⇒ 2x= 170  (∵ -y+y=0)

                   ⇒x = 170/2

                 ⇒  x = 85

substitute x in equation 1 (or equation 2.its your choice. you'll get the same answer)

equation 1 → x-y=30

                      85-30 = y  (substituting x and bringing 30 on one side and y on one side)

                    55 = y

∴x=85

 y=55

hope it will be helpful to you ✌️
