Question

the three angles of a triangle are 2x , (3x-2 ) and (7x-10).Find the angles .​

Answer 1

here's ur answer

angle sum of property of triangle=180

so

2x+3x-2+7x-10=180

12x-12=180

12x=180+12

12x=192

x=192/12= 96/6 =48/3 =16

so x=16

2x=2*16=32

3x-2=3*16-2=48-2=46

7x-10=7*16-10=112-10=102

Answer 2

The three angles of a triangle are 32°, 46° and 102°.

Step-by-step explanation:

The sum of the angles of a triangle is 180°.

The three angles of a triangle are:

2x, (3x - 2) and (7x - 10)

Compute the value of x as follows:

2x + 3x - 2 + 7x - 10 = 180°

                   12x - 12 = 180°

                          12x = 192°

                              x = 16°

The three angles are:

2x = 2 × 16° = 32°

3x - 2 = (3 × 16°) - 2 = 46°

7x - 10 = (7 × 16°) - 10 = 102°

Thus, the three angles of a triangle are 32°, 46° and 102°.
