Question

ans this fast ques 10

Answer 1

Answer:

angel a = 36, b= 54, c=90

Step-by-step explanation:

total of angels of a triangle is 180

so

angle a = 180/10*2=36

angle b= 180/10*3= 54

angle c = 180/10*5=90

Answer 2

Answer:

Let us take the given ration be 2x : 3x : 5x.

Then, the sum of angles = 2x + 3x + 5x = 10x

But the angle sum property of a ∆ is 180°.

So, ATQ, 10x = 180°.

Therefore x = 18°.

So, the first angle = 2x = 2 ×18° = 36°.

Second angle = 3x = 3 × 18° = 54°.

Third angle = 5x = 5 × 18° = 90°.
