Answer:

Step-by-step explanation:

If angle 5 = 4x + 15, and angle 4 = 6x - 5, and angle 5 = angle 4, then:

4x + 15 = 6x - 5 and

20 = 2x so

x = 10. Now sub this back in for x in angle 5's expression:

angle 5 = 4(10) + 15 ---> 40 + 15 ---> angle 5 = angle 4 = 55 degrees

w represents width

4w represents length

d represents diagonal

w2 + (4w)2 = d2

w2 + 16w2 = d2

17w2 = d2

±w√17 = d

The diagonal is the width times √17.
