Answer:
As in this case where the adjacent angles are formed by two lines intersecting we will get two pairs of adjacent angles (G + F and H + E) that are both supplementary. Two angles that are opposite each other as D and B in the figure above are called vertical angles. Vertical angles are always congruent
Step-by-step explanation:
D + 15 - 9 / 3 + 5 the answer is : d + 17
So all you need to do in order to find the sum is add so 185+66=251
Answer:
C
Step-by-step explanation:
according to the standard equation;
Y=mX+C
or, Y=4/5X +3
Answer:
Step-by-step explanation:
The angles forming a straight angle are supplementary.
We have angles APC and DPB forming a straight angle with adjacent angle to both (either angle APD or CPB).
It means the correct choice is D.
