What is the value of x in the figure?

Mathematics

Answer:

Step-by-step explanation:

Opposite sides are parallel and equal. So, ABCD is a parallelogram

In  ΔABD,

∠A + ∠ACB + ∠ABC = 180  {Angle sum property of triangle}

∠A + 80 + 20 = 180

∠A + 100 = 180

∠A = 180 - 100

∠A = 80

In parallelogram, opposite angles are equal.

∠D = ∠A

x° = 80°

180 - (80 + 20) = 80

angle BAC = 80
opposite angles are equal for parallelogram so x = 80 too:)

sorry if it’s incorrect :/

A certain forest covers an area of 4000 km2. Suppose that each year this area decreases by 7%. What will the area be after 5 yea
Levart [38]
Answer:

2,600

Explanation:

Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.

Which equation represents a circle that contains the point (-2, 8) and has a center at (4, 0)
nevsk [136]

Answer:

Option 1:(x-4)^2+y^2=100

Step-by-step explanation:

Given center = (h,k) = (4,0)

The point (-2,8) lies on circle which means the distance between the point and center will be equal to the radius.

So,

The distance formula will be used:

d = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}} \\=\sqrt{(4+2)^{2}+(0-8)^{2}}\\=\sqrt{(6)^{2}+(-8)^{2}}\\=\sqrt{36+64}\\ =\sqrt{100}\\ =10\ units

Hence radius is 10.

The standard form of equation of circle is:

(x-h)^2+(y-k)^2 = r^2

Putting the values

(x-4)^2+(y-0)^2=10^2

(x-4)^2+y^2=100

Hence option 1 is correct ..
