Answer 4

ok, so u know how 1 full revolution is 360 degrees?

Answer 5

yes

Answer 6

cool, so it's just algebra from here
you have a straight line, so half a revolution, so half of 360, so total is 180 degrees

Answer 7

so solve for x first, then solve for m<DBC
7x + (x-4) = 180
can u solve for x from here?

Answer 8

I have a triangle not a circle

Answer 9

x=23

Answer 10

u have a straight line that is bisected, so ignore the bisection and concentrate on the straight line first
straight line = 18 degrees

Answer 11

*180 degrees

Answer 12

yep, perfect
so x = 23

Answer 13

ur angle DBC is x-4
so 23-4 = ur angle

Answer 14

okay ty

Answer 15
