Answer 1

100°is the correct answer

Answer 2

Step-by-step explanation:

so according to question

let the angle beside 45 degree be x

now if we draw a line BD ,so angle B would be 90

so, x +45 degree =90degree

x=90 -45

x=45

now let the angle beside 108 degree be y

so, y+ 108=180

y=72

now OBD is becoming a triangle

so we have got two angles of a triangle

hence the 3rd angle will be

180 -(72 +45)

180 -117

63

so the value of angle ODC is 180 - 63=117
