c²= √9²+11²
c=√202
c=14.21
I went in order from top to bottom. don't know if this was what you meant...... (1,2), (2,-2), (3,-6), (4,-10).
Not easy to graph but
multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton
2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5
subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5
x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)
Answer:
First find the inner angle:
[ given hypotenuse = 500 ft ]
using sine rule:




using pythagoras theorem:
Draw the figure out and you will find that AB + BC = AC. Given this, put the equations together to form x+41+x+10=22. Solve to get x=-29/2
