What is the best next step in the construction of a line that passes through point c and is parallel to ab? (assume that the arc drawn with the compass placed at point a was the result of the last step performed.)

a. using the same compass setting, place the point of the compass at b and draw an arc that intersects ab.

b. change the compass setting, and draw an arc with point of the compass at point a that passes through point b.

c. using the same compass setting, place the point of the compass at c and draw an arc that intersects ab.

d. change the compass setting, and draw an arc with point of the compass at point a that passes through point c.

d is ur answer hopes this i dont really know how to explain it to u.

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

what am i trying to find out. you didn't put up the whole question.

step-by-step explanation:

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
