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:
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
