Answer:

x = 40

Step-by-step explanation:

As the Corresponding angles are equal

4x - 50 = 2x + 30 \\ 4x - 2x = 50 + 30 \\ 2x = 80 \\  \frac{2x}{2}  =  \frac{80}{2}  \\ x = 40 \degree

Hope this helps you.

Let me know if you have any other questions :-)

A rectangle is removed from the middle of a larger rectangular shaped board. What is the area of the remaining board?
jeyben [28]

Answer:

The area of the remaining board is [(L × B) - (l × b)].

Step-by-step explanation:

Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.

Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.

The area of any rectangle is:

Area = Length × Breadth

The area of the bigger rectangle is:

Area of ABCD = L × B

The area of the smaller rectangle is:

Area of PQRS = l × b

Then the area of the remaining board will be:

Area of remaining board = Area of ABCD - Area of PQRS

                                         = (L × B) - (l × b)

Thus, the area of the remaining board is [(L × B) - (l × b)].
