Answer 3

1. Stating the correct angle
2. Explanation is correct
3. Using proper grammar

Answer 4

2y - 5 = 95 So 2y = 100 So y = 50
and 3x + 55 = 85 So 3x = 30 So x = 10

So x + y = 10 + 50 = 60

Answer 5

I am not good at geometry, but I can tell you that < BKC is 90 degrees

Answer 6

The angle is BKC because it is equal to the sum of angle BKD and DKC.

Answer 7

BKD=70 degrees DKC=20 degress
70+20=90
