Question

I’m confused on this one

Answer 1

So for this, remember that

1. a property for parallelograms is that opposite angles are congruent

and 2. all angles add up to 360

Using this info, we can form the equation
`136*2+x*2=360`

So firstly, solve the multiplications:
`2x+272=360`

Next, subtract 272 on each side:
`2x=88`

Finally, divide 2 on each side of the equation, and your answer should be
`x=44`

In short, ∠BCD is 44°
