Answer:

B) √229

Step-by-step explanation:

√229 is about 15.13, which is the approximate location of point B.

IMO, the dot at point P is a little too far to the right for √229.

Answer:

The correct answer is A. 144 inches².

Correct statement is attached:

Determine the surface area of the figure if the height of the triangular face is 6 inches. The triangles are equilateral.

A. 144 inches²

B. 133 inches²

C. 150 inches²

D. 160 inches²

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Height of the triangular face = 6 inches

Length of the long side of the triangular prism = 10 inches

Length of the short side of the triangular prism = 4 inches

The triangles are equilateral

2. Determine the surface area of the figure if the height of the triangular face is 6 inches. The triangles are equilateral.

For calculating the answer, we need to know what is the surface of the five faces of the triangular prism.

We have three rectangular faces and two triangular faces.

Surface area of the rectangular faces = Length * Height

Surface area of the rectangular faces = 10 * 4 = 40 inches²

Surface area of the triangular faces = (Length * Height)/2

Surface area of the triangular faces = 6 * 4/2 = 12 inches²

Now the total surface area of the five sides is:

3 * Surface area of the rectangular face + 2 * Surface area of the triangular face

3 * 40 + 2 * 12 = 120 + 24 = 144 inches ²

The total surface area of the five faces is A. 144 inches ²

Please help me 100 points and brainliest Which net represents this solid figure?

Contact [7]

The one you picked, on the bottom left is correct

The top two both have rectangles and triangles, making them most likely triangular prisms. To the bottom right, the net represents a cube, which is incorrect, because the figure is supposed to be a rectangular prism.

Analyze the diagram below and complete the instructions that follow.

docker41 [41]

Answer:

x = 8 sqrt(2)

Step-by-step explanation:

Since this is a right triangle

sin 45 = opp side/ hypotenuse

sin 45 = 8/x

Multiply each side by x

x sin 45 = 8/x *x

x sin 45 = 8

Divide each side by sin 45

x sin 45 /sin 45 = 8 /sin 45

x = 8 / sin 45

We know sin 45 = 1/ sqrt (2)

x = 8 / 1 / sqrt(2)

x = 8 sqrt(2)

He measure of one angle of an octagon is twice that of the other seven angles. what is the measure of each angle? answer: ,

Scrat [10]

Answer:
measure of larger angle = 240 degrees
measure of each of the smaller angles = 120 degrees

Explanation:
In any polygon, the sum of measures of interior angles can be calculated using the following rule:
sum of interior angles = (n-2)*180 where n is the number of sides

Now, for an octagon, n=8, this means that:
sum of measures of interior angles = (8-2)*180 = 1080°

An octagon has 8 interior angles, one of which is twice the measure of the others.
Assume that each of the 7 smaller angles is x degrees and that the larger angle is 2x degrees

Computing their summation, we will find that:
x + x + x + x + x + x + x + 2x = 1080
9x = 1080
x = 120

This means that:
each one of the smaller angles = x = 120 degrees
the larger angle = 2x = 2 * 120 = 240 degrees

Hope this helps :)
