Answer 1

Answer:

angle aoc =40degrees angle box =40degrees

Answer 2

Answer:

AOC= 64°

BOC= 126°

Step-by-step explanation:

Given- AB and CD are the intersectors of point O

AngleAOC and AngleBOC = 3:7

Find- a) AOC

b) BOC

To find -

Let the AOC be 3x and BOC be 7x

AOC+BOC=180°

3x+7x=180°

10x=180°

x=180

10

x=18°

Angle AOC = 3x = 3×18° = 64°

Angle BOC = 7x = 7×18° = 126°

Here's ur answer
