The only math term I can think of is geometry and it means when a solid is cut through parallel to the base.
EDIT: After further research since it was all I could think of. This is the only math term for what you are looking for.
Let us say that:
x = cost of shorts
y = cost of slacks
z = cost of sports coat
From the given statements, we can create the following
equations:
eqtn 1: 3 x + y =
10.96
eqtn 2: 7 x + 2 y +
z = 30.40
eqtn 3: 4 x + z =
14.45
Rewrite eqtn 1 explicit to y:
y = 10.96 – 3 x -->
eqtn 4
Rewrite eqtn 3 explicit to z:
z = 14.45 – 4x -->
eqtn 5
Plug in the values of y (eqtn 4) and z (eqtn 5) to eqtn
2:
7 x + 2 (10.96 – 3 x) + 14.45 – 4 x = 30.40
7 x + 21.92 – 6 x + 14.45 – 4 x = 30.40
- 3 x + 36.37 = 30.40
- 3 x = - 5.97
x = 1.99
Eqtn 4:
y = 10.96 – 3 x
y = 10.96 – 3 (1.99)
y = 4.99
Eqtn 5:
z = 14.45 – 4x
z = 14.45 – 4 (1.99)
z = 6.49
Therefore each shirt cost $1.99, each slacks cost $4.99,
and each sports coat cost $6.49.

Answer:
![b=40.01\ units](https://tex.z-dn.net/?f=b%3D40.01%5C%20units)
Step-by-step explanation:
we know that
Applying the law of sines
![\frac{b}{sin(B)}=\frac{a}{sin(A)}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bsin%28B%29%7D%3D%5Cfrac%7Ba%7D%7Bsin%28A%29%7D)
![b=\frac{a}{sin(A)}(sin(B))](https://tex.z-dn.net/?f=b%3D%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%28sin%28B%29%29)
we have
![a=25\ units](https://tex.z-dn.net/?f=a%3D25%5C%20units)
![A=32.5\°](https://tex.z-dn.net/?f=A%3D32.5%5C%C2%B0)
Find the measure of angle B
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
so
![A+B+C=180\°](https://tex.z-dn.net/?f=A%2BB%2BC%3D180%5C%C2%B0)
substitute the given values
![32.5\°+B+26.8\°=180\°](https://tex.z-dn.net/?f=32.5%5C%C2%B0%2BB%2B26.8%5C%C2%B0%3D180%5C%C2%B0)
![B=180\°-59.3\°=120.7\°](https://tex.z-dn.net/?f=B%3D180%5C%C2%B0-59.3%5C%C2%B0%3D120.7%5C%C2%B0)
Find the length side b
![b=\frac{a}{sin(A)}(sin(B))](https://tex.z-dn.net/?f=b%3D%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%28sin%28B%29%29)
substitute the values
![b=\frac{25}{sin(32.5\°)}(sin(120.7\°))](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B25%7D%7Bsin%2832.5%5C%C2%B0%29%7D%28sin%28120.7%5C%C2%B0%29%29)

Hello :
by moivre theorem :
[2(cos15*+isin15*)]^3 = 2^3(cos(3×45*)+isin(3×45*))
=8 (cos45*+isin45*)
= 8 ( √2/2 +i √2/2)
= 4√2 + 4√2 i ..... ( <span>in standard form a+bi)
</span>a = b = 4√2
