Look at δabc and its 90° rotation.   if ab is 8 inches long, what is the length of a'b' ?

Because the triangle is only rotated, AB and A'B' would be equal. 8 in.

c. 4 1/4 pounds

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
