Can you put a picture so we can see what it look like
Answer:
Step-by-step explanation:
12.5z - 6.4 =-8z + 3(1.5z - 0.5)
12.5z - 6.4 = - 8z + 4.5z - 1.5
12.5z - 6.4 = - 3.5z - 1.5
Bringing like terms on one side
12.5z + 3.5z = - 1.5 + 6.4
16z = 4.9
z = 4.9/16
The increase of volume = volume of the cube = 1 cubic foot = 1728 cu ins
Area of the base = 12 sq ft = 12 * 144 = 1728 sq ins
The height of increase = 1728 / 1728 = 1 inch Answer
1. By the Law of Sines, you have:
SinA/a=SinB/b=SinC/c
2. You don't need the fraction SinC/c, so you can eliminate it. Then:
SinA/a=SinB/b
A=40°
a=19
B=m∠b
b=13
3. When you substitute this values into SinA/a=SinB/b, you obtain:
SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°
Therefore, the answer is: 26.1 degrees.
