Simplify the expression.
-9(8 + 6n-4) = ?

30

step-by-step explanation:

times by times

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
