Question

calculate the measure of angle aoc if angle bao =40 degree and angle boc =40 degree

Answer 1

Answer:

aoc =x bao is 40 boc was is 40 so bao + boc=aoc so 40+40 =80...

Answer 2

Answer:

190

Step-by-step explanation:

angle ABC = 90°

{ angle in semicircle is always = 90° }

angle BAO = 40° { Given }

angle BCO = 49° { Given }

Now in ABOC,

angle ABC + BAO + BCO + AOC = 360°

90° + 40° + 40° + angle AOC = 360°

170 +AOC=360

angle AOC=190°
