Step-by-step explanation:
8/3 = 2 2/3 and -11/3 = -3 2/3
so the middle line is 0 and each big line is 1.
Put the first dot on 2 2/3 or right before the 3rd big line.
Put the second dot on -3 2/3 or the line right after the 4th big line going back from 0
Answer:13.5 inches
Step-by-step explanation:
Given diagonal as 15.6inches
Width is unknown
Height is 7.8 inches
From the diagram attached it forms a right angle solved using Pythagoras theorem
Ie
15.6^2=width^2+7.8^2
Width= ✓(15.6^2-7.8^2)=13.5inches
