If m angle ecd is six less than five times m angle bce, and mangle bcd = 162º. find each
measure.

see explanation

Step-by-step explanation:

let ∠BCE = x then ∠ECD = 5x - 6 and

∠BCE + ∠ECD = ∠BCD, substitute values

x + 5x - 6 = 162, that is

6x - 6 = 162 ( add 6 to both sides )

6x = 168 ( divide both sides by 6 )

x = 28

Hence

∠BCE = x = 28°

∠ECD = 5x - 6 = (5 × 28) - 6 = 140 - 6 = 134°

the correct is answer is a 9-sided polygon!

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
