Answer:

17. angle DAB=118º

18. angle DAB=126º

Step-by-step explanation:

The angle A should be 180º-85º-33º(cause the total angle in a triangle is 180º)

So you will get 62º as the angle of A.

And what the question ask is angle of DAB,so again 180º-62º=118º(A straight line is 180º)

Same goes to question 18,use 180º to minus the two angle given,you get 54º ,and then 180ºminus 54º again,the answer is 126º
