Describe the transformations that will map triangle A to triangle B and illustrate the similarity between the two triangles. A)reflect triangle a across the y-axis and then translate triangle a 5 units down.  B)reflect triangle A across the x-axis and then reflect triangle a across the y-axis.  
C)translate triangle a 4 units down and then rotate triangle A 180° counterclockwise about the origin. 
D)reflect triangle a across the x-axis and then rotate triangle A 90° counterclockwise about the origin

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.

Select the correct answer. what is the exact value of sin (157.5°)? a. 'sqrt(2 - sqrt(2))/2 b. *"-"'sqrt(2 + sqrt(2))/29 c.'sqrt(2 + sqrt(2))/4" d. "-"sqrt(2 + sqrt(2))/4)
