Given ABC=65 and BCD=105. Is it possible that Line AB intersects line CD

levacccp [35]

Given:

$m\angle ABC=65^\circ$

$m\angle BCD=105^\circ$

To find:

Whether it is possible that Line AB intersects line CD.

Solution:

We have,

$m\angle ABC=65^\circ$

$m\angle BCD=105^\circ$

The angles $m\angle ABC$ and $m\angle BCD$ are same sided interior angles.

If two lines are parallel and a transversal line intersect them, then the same sided interior angles are supplementary angles and their sum is 180 degrees.

$m\angle ABC+m\angle BCD=65^\circ+105^\circ$

$m\angle ABC+m\angle BCD=170^\circ$

$m\angle ABC+m\angle BCD\neq 180^\circ$

So, the lines AB and CD are not parallel to each other.

Therefore, the intersection of lines AB and CD is possible.

Assuming the volume of a trigonal prism, who has a side of 10cm and a length of 20 cm, is 866cm^3, what is its surface area?

Leno4ka [110]

The surface area of the triangular prism is 686.6 cm².

Step-by-step explanation:

Step 1:

The volume of a triangular prism can be determined by multiplying its area of the triangular base with the length of the prism.

The base triangle has a base length of 10 cm and assume it has a height of h m.

The volume of the prism $= \frac{1}{2} (b)(h) (length) = \frac{1}{2} (10)(h)(20) = 866.$

$h = \frac{866(2)}{10(20)} = 8.66.$

The height of the triangle is 8.66 cm.

Step 2:

The surface area of the triangle is obtained by adding all the areas of the shapes in the prism. There are 2 triangles and 3 rectangles in a triangular prism.

The triangles have a base length of 10 cm and a height of 8.66 cm. A triangles area is half the product of its base length and height.

The rectangles all have a length of 20 cm and a width of 10 cm. The area of a rectangle is the product of its length and width.

The area of the 2 triangles $= 2 [\frac{1}{2} (10)(8.66)] = 86.6.$
