The two angles form a right triangle which is 90 degrees.

Add the two to equal 90:

3x-8 + 4x = 90

simplify:

7x-8 = 90

Add 8 to both sides:

7x = 98

Divide both sides by 7:

x = 14

Tom wants new carpeting for his bedroom. His room is a 999 meters by 777 meters rectangle. How much carpeting does he need to bu
fomenos

Answer:

777,223 meters squared

Step-by-step explanation:

To find the amount of carpeting, we must find the area of the floor of Tom's bedroom.

To find area, we multiply the length and width of the rectangle.

999 x 777 = 776,223

Remember, when we find the area, we must give the answer in square units.

Our final answer is 777,223 meters squared

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.
