The two triangles shown in the figure are similar. find the distance, d, across coyote ravine.

d=157.5 meters

Step-by-step explanation:

I used proportion for this case, since it is known that side lengths of two similar triangles are proportional.

Take 180, divide by 400 to get the proportional increase in size.

Then multiply that number by 350, since that is the corresponding side of the similar triangle.

This would be:

180/450= 0.45

0.45*350=157.5

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
