Question

if three angles of a triangle are 3x-40degree x+15 degree and 2x-35 degree then x equals to - 30 , 40 , or 35

Answer 1

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!
