Question

find the value of x in the given figure​

Answer 1

Answer:

14

Step-by-step explanation:

all the angles make a linear pair

sum of all angles = 180°

so,

$(6x - 40) + (5x + 9) + (3x + 15) = 180 \\ \\ 6x + 5x + 3x - 40 + 9 + 15 = 180 \\ \\ 14x - 16 = 180 \\ 14x = 180 + 16 \\ 14x = 196 \\ \\ x = 196 \div 14 \\ x = 14$
