Find the value of x.

Mathematics
1 answer:
andrew11 [14]3 years ago
5 0

Answer:

50

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360            Equation. Combine like terms.

2x + 260 = 360                         Subtract 260 from both sides

2x = 360 - 260                    

2x = 100                                    Divide by 2

x = 100/2

x = 50

Which of the following is the area of a quadrilateral with vertices at (-4,2),(1,2),(1,-3) and (-4,-3)
kow [346]

Answer:

The correct option is B.

Step-by-step explanation:

The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).

Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Use distance formula to find the side length.

AB=\sqrt{(1-(-4))^2+(2-2)^2}=\sqrt{5^2}=5

BC=\sqrt{(1-1)^2+(-3-2)^2}=\sqrt{(25}=5

Since both consecutive sides are equal therefore it is a square.

Area of a square is

A=a^2

Where, a is side length.

The side length of the square is 5. So, area of ABCD is

A=(5)^2

A=25

Therefore the area of quadrilateral is 25 units square. Option B is correct.
