Answer 2

Answer:

40∘, 50∘ and 90∘

Step-by-step explanation:

Let the two angles of the triangle be 4x and 5x. 

Then, as per the question, we know

third angle =4x+5x=9x

We know that sum of all the angles of a triangle is 180∘.

∴4x+5x+9x=180∘⇒18x=180∘⇒x=10∘    ....[On dividing both sides by 18]

So, first angle = 4x∘ = 4×10∘=40∘,

second angle = 5x∘ = 5×10∘=50∘ and

and third angle = 9x∘ = 9×10∘=90∘

I hope this is helpful...
