∠C and ∠D are vertical angles.
denis-greek [22]

Vertical angles is the same angle, but we don't know "x". If you look in a way. We can do 180=(3x+80).

100=3x

100/3 = x

Now we have the answer for x we plug it in to get the answer.

3(100/3) + 80 =<D

<D = <C

I'm a little confused, it's about Combining like terms but I did don't understand​
ella [17]
2(-n-3)-7(5+2n)

First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.

2 times -n= -2n

2 times -3= -6

-7 times 5= -35

-7 times 2n= -14n

This leaves you with

-2n -6 -35 -14n

Next, combine like terms.

(-2n) + (-14n)= -16n
(-35) + (-6)= -41

This gives you

-16n-41, which is B in your answer choices.

Hope this makes sense!! :)
