Answer:
hey here is your answer....!!
Step-by-step explanation:
We know that the sum of all angles of a triangle are 180.
______________________*_________________________
Given :- Angles are 3x - 40 , x + 15 , and 2x - 35
So we have to add all angles to get 180
----------------------------------------------------------------------------
- (3x - 40) + (x + 15) + (2x - 35) = 180
- (3x + x + 2x) + (15 - 40 - 35) = 180
- 6x - 75 + 15 = 180
- 6x -60 = 180
- 6x = 180 + 60
- x = 240 / 6
- x = 40
So the value of x is 40.
___________________________________________
Three angles will be
x + 15 = 40 + 15 = 55
3x - 40 = 3(40) -40 = 80
2x - 35 = 2(40) -35 = 45
-------------------------*-------------------------------------------
Sum of all sides is 55 + 80 + 45 = 180.
Hope it helps!
