Answer 2

I think the answer is B.

Answer 3

@tkhunny

Answer 4

a right angle is 90 degrees. the two angles <CDG + <GDF add up to 90

Answer 5

so 35 + <CDG = 90

Answer 6

35+55=90

Answer 7

you can test each answer, or you can use "algebra"
<CDG= 90 - 35

Answer 8

90-35=55

Answer 9

oh by the way I am not new I just created myself a new profile , my old profile name was rainbow_rocks03

Answer 10

in case you do not know, if you are able to write
<CDG + 35 is 90
or
<CDG+ 35= 90
then "add -35" to both sides like this
<CDG + 35 + -35 = 90 + -35
and simplify

on the left side +35-35 is 0 and <CDG + 0 is <CDG
on the right side you get 55
<CDG = 55

Answer 11

So my answer is 55 ?
