Question

The angles of a triangle are 3x",5x",7x"+15.find the largest angle . 5x4 and 7x + 15. Find the largest angle.​

Answer 1

Answer:

may b dis 1..!

Step-by-step explanation:

Size of angles of a triangle =

3x, 5x and 4x..

We know that the sum of the angles of a triangle = 180°

Therefore,

3x + 5x + 4x = 180°

12x = 180°

x = 180°/12

x = 15°

So, the sides of the triangle =

3x

= 3*15

= 45°

5x

= 5*15

= 75°

4x

= 4*15

= 60°..

Verification,

45° + 75° + 60° = 180°

180° = 180°

So, the smallest angle is 45°...
