Question

the angle of a triangle are X + 10 X + 40 and X - 30 find the value of x​

Answer 1

Answer:100/3

Step-by-step explanation:

(x+10)+(x+40)+(x-30)=180   (angle sum)

3 x+80=180

3 x=180-80

3 x= 100

x = 100/3.

Answer 2

Answer:

x+10x +40 +x-30 =180 (sum of the angels of a triangle is 180°)

12x+10=180

12x=180-10

12x=170

x=170/12

x=14.166....
