Answer 1

Step-by-step explanation:

QUESTION ;

The 3 angles of a triangle are in the form of the ratio 8:5:4find the angles of the triangle

METHOD TO SOLVE :

By letting the angle as 8x , 5x and 4x and after doing sum of all term and equating 180° from it, we get the value of x and by multiplying the value of x to each term , we get the value of every terms

SOLUTION ;

Let, the angle be 8x , 5x and 4x

according to sum of interior angle of triangle,

8x + 5x + 4x = 180°

17x = 180°

x = 180/ 17

x = 10.58 °

Now,

8x = 8 x 10.58 = 84.64°

5x = 5 x 10.58 = 53°

4x = 4 x 10.58 = 42.36° answer
