Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
<h2><em><u>
2/9 is the answer.</u></em></h2>
Step-by-step explanation:
<em><u>1. First, make an equation.</u></em>
<em><u>Given:</u></em>
8/9 = length of wire
2/3 = length of a part of the wire
E = 8/9-2/3
<em><u>Unknown:</u></em>
Second part of wire
<em><u>2. Make the numbers have equal denominators</u></em>
2/3 * 3/3
= 6/9
<em><u>3. Solve</u></em>
8/9 - 6/9
= 2/9

It doesn’t bother me that much but it’s understandable
Answer:
angles 3, 1, 7, 5
Step-by-step explanation:
suplementary angles add up to 180 degrees so
<4 + <3=180
<4 + <1 =180
<4 + <7=180
<4 + <5= 180
