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
mark as brainliest plz ❤️❤️

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°.
