Question

if the angle of a triangle are (3x°) , (2x -7)° and (4 x +11 )° , find the value of x.​

Answer 1

Answer:

see below

Step-by-step explanation:

do sum of all three and equal it to 180 degrees

3x+2x-7+4x+11=180

9x+4=180

x=176/9

Answer 2

Answer:

19.5

Step-by-step explanation:

3x + (2x-7) + (4x+11) = 180  (sum of all angles of a triangle is 180)
3x + 4x + 2x + 11 -7 = 180
9x + 4 = 180
9x = 180 - 4
x = 176/9
x = 19.5

I think there is something wrong with the question, but this is the best i can do
