Answer:
5 degrees
Step-by-step explanation:
5 + x=0
-5 -5
×= -5
Answer:
x=3
y=13
Step-by-step explanation:
okay so what that means is that the two equations are y=-x+16 and y=3x+4
so y+x=16
y-3x=4
so 4x=12 so x=3
y=13 is the solution
Answer:
7384
Step-by-step explanation:
Since a square is equal on all 4 sides, that means each side would be 5, because 20/4=5
so using the Pythagorean thrm (which we can use since a square has all 90 degree angles)
a=5 b=5 c=?
5^2+5^2=c^2
25+25=c^2
50=c^2 *square root both sides*
c= 7.07
So the answer would be 7.1
