Answer:
The answer to your question is x = 3.356 cm
Step-by-step explanation:
This is a right triangle so we can use the Trigonometric functions to solve this problem.
Data
Ф = 40°
Adjacent side = 4 cm
Opposite side = x
Process
1.- We must know the lenght of the opposite side so we must use the tangent to solve it.
tangent Ф =
2.- Solve it for Opposite side
Opposite side = tanФ x Adjacent side
Opposite side = tan 40° x 4
Opposite side = 0.839 x 4
Opposite side = 3.356
Opposite side = x = 3.356 cm
Answer:
x ≈ -0.24
Explanation:
Using a graphing tool to graph the given equation, we will end up with the graph shown in the attached image.
Now, to solve the equation means to find the x-intercept.
Taking a look at the graph, we would find that the x-intercept is somewhere between the -0.2 and the -0.3
This means that the best choice is x ≈ -0.24
We can check using algebraic substitution:
-3x + 2 = -3(-0.24) + 2 = 2.72
4ˣ +2 = 4⁻⁰.²⁴ + 2 = 2.7169
We can note that the two values are almost equal.
Hope this helps :)

The match up are:
- 64 inches : cross-section, cube, 16 inches
- 26 inches : right rectangular prism, 10x 3 x 14 inches
- 48 inches : cube with 12-inches edges
- 34 inches : rectangular prism, 5x12x4 diagonal of 13 inches
A prism is known to be a kind of 3-dimensional shape that has two similar shapes that are known to be facing each other.
Note that:
Right rectangular prism == 10x 3 x 14 inches
Since the cross-section is known to be parallel to the base, then:
P = 10 + 3 + 10 + 3
= 26 inches
For cube that has 12-inches edges
We say that;
P = 12 + 12+ 12 + 12
= 48 inches
For rectangular prism that has 5x12x4 diagonal of 13 inches
We say that:
P = 13 + 4 + 13 + 4
= 34 inches
For cross-section cube that 16 inches,
we say that:
P = 16 + 16 + 16 + 16
= 64 inches.
