Answer:
15
Step-by-step explanation:
It is a right angle so it will add up to 90 degrees.
This is the equation:
x=90-19-56
x=15
3*3+4*4=x*x and 9+16=25 so x is 5 and then add other sides so 5+8+4+5
Answer:
16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)
Step-by-step explanation:
Your slope is -5
y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y
-5=-5(-3)+b, solve for b
-20=b, now rewrite the equation
y=-5x-20
Your slope is 6
y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y
0=6(-3)+b, solve for b
18=b, now rewrite the equation
y=6x+18, or factored y=6(x+3)
