Answer:

(3x+7) + (9x+17) = 180(it's a strait line)

3x+9x+7+17=180

12x+24=180

12x=180-24

12x=156

x=156/12

x=13

ANSWER ASAP PLEASE
ruslelena [56]

Answer:

jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct

Step-by-step explanation:

so, all angles of a triangle have to add up to 180;

(15x) + (8x - 11) + (3x + 9) = 180

15x + 8x - 11 + 3x + 9 = 180

add your common numbers

26x - 2 = 180

add 2

26x = 182

divide 26

x = 7

put it back into the equation

15(7) + 8(7) - 11 + 3(7) + 9 = 180

180 = 180
