Answer:
m<ABC=40
Step-by-step explanation:
Ok so we need to break up this problem.
m<ABC=4x
m<BCA=7x-20
m<A= 90 degrees (We are given a right angle here)
Because of the Triangle Sun Theorem, all the angles here would add up to 180 degrees. So..
4x+7x-20+90=180
Solve
x=10
Then we look back and see that m<ABC is 4x
We plug in x
4(10)=m<ABC
m<ABC=40

Step-by-step explanation:
Your slope is 
and your y-intercept is -3. Plot your y-intercept on the y axis at -3 and then go up 3 and over 2, plot another point.
Hope this helps! :)

Answer:
V = 24416.6
Step-by-step explanation:
V = 4/3 pi r^3
V = 4/3 (3.14) 18^3
V = 4/3 (3.14) 5832
V = 4/3 (18312.48)
V = 24416.64
