If angle ABC = 105° is bisected by an angle bisector EF , then measure of angle FBC is : a) 52
b) 52.5°
c) 62.5°
d) 62°
tell me pwease​

B) 52.5°

Bisect means in half and half of 105° is 52.5°

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
