Answer correct I will mark as brain list ​

Answer 1

Step-by-step explanation:

1) Sum of all angles of a triangle is 180 degrees.

(5x-60) + (2x+40) + (3x-80) = 180

10x -100 = 180

10x = 180 + 100

10x = 280

x = 28 degrees

Like this by using the above property you can find your all answers.

Hope this helps!
