1. b=117°

2.c=67°

have an amazing day <3

1) 117 degrees

If angle A and angle B aré supplementary this means that they add up to 180 degrees

180 degrees - 63 degrees leaves us with 117 degrees for number 1

2) 67 degrees

If angle C and angle D are complementary, this means they add up to 90 degrees

90 degrees - 23 degrees = 67 degrees

Hope this helps :)
