Ok so the first thing you want to do is find the area of the front triangle.
14x10=140
140/2=70
So you have the area of the triangle
Now you just need to times it by 19 to get the depth
70x19=1330
Answer
1330 inches cubed

Answer:
D
Step-by-step explanation:
72/2=36
36/2=18
18/2=9
9/3=3
2,2,2,3,3
Let’s call the numbers x and y. Let’s also say that x is the smaller of the two. Since their difference (the answer you get when you subtract is 44 and a half) we know that y-x=44.5
Next we are told that if the smaller increases 7 times (that means 7x) their difference would be 10 3/14. Let’s write that as a fraction. It is 14x10+3 over 14. That is 143/14.
So this means y-7x=143/14.
We have two equations and two unknowns (a system of equations). We write one over the other and subtract them to get:
y-x=44.5
y-7x=143/14
Subtracting yields:
(y-y)+(-x - - 7x) = 44.5 - 143/14
6x = (89/2) - (143/14)
6x= 623/14 - 143/14
6x=480/14
X= (480/14)(1/6)
X=80/14
x= 40/7 = 5 5/7
Since y-x=89/2
We get y - 40/7 = 89/2
Y = 40/7 + 89/2
Y = 80/14 + 623/14
Y = 703/14 = 50 3/14
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
X=60
Y=120
Z=60
Hope this helps
