The second angle of a triangle is 50° less than the first angle the third angle is 40° less than the first angle find the measurements of all three angles

First angle =

Secomd angle  =

Thirsd angle   =  

Step-by-step explanation:

Let  the first angle be x------------(1)

Then the second angle is 50° less than the first angle

Then the second angle will be x -50------------(2)

The third angle is 40° less than the first angle

Then the angle will be x - 40------------(3)

We know that, according to angle sum property , the sum of all the three angle will be 180 degrees

So adding all the 3 angles,

Now the second angle is

=>

=>

=>

The Third angle is

=>

=>

=>
