Answer:
x = 3.64°
Explanation:
Okay, so assuming that all those cute little lines add up to make m<BCD equal to m<EBC, because if they're not, we're screwed, let's go:
So, m<BCD is 55°, so that means that m<EBC or (14x + 4)° should equal 55°, this calls for a nice algebraic expression:
14x + 4 = 55
And we do the inverse operation thing:
55 - 4 = 51
51 ÷ 14 = 3.64 (rounded)
So x = 3.64°
sorry if this is wrong
hope this helps:)
