I really need help with this question i’m rlly confused (I’ll give brainliest!!)

4x + 5x + 9 = 180 ( sum of co-interior angles)

or,9x + 9 = 180

or,9x = 180 -9

or,9x = 171

or, x = 171÷9

:.` x = 19

i do not know the answer i am sorry

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
