Question

please answer the question ​

Answer 1

∠C= 45°

∠D  :

Let the angle be x,

100+45+x = 180°  {Using the angle sum of a triangle is 180°}

145+x= 180

x= 180-145

x= 35°

∠ODC= 35°

Answer 2

Answer:

35 degree

Step-by-step explanation:

ang ABO = ang OCD = 45 degree

in tri COD

by ang sum prop

100 + 45 +ODC =180

therefore ODC =35 degree
