The diagonal of a monitor that is 5 inches wide and 12 inches

I'm not sure if you forgot to add the rest of the question, but does this help?

Step-by-step explanation:

If you are using the pythagorean theorem you would a^2 + b^2 = c^2. 5 = 25, 12 = 144.

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

angle addition postulate

2x=56
