Answer:

x = 83 degree

Step-by-step explanation:

x + 43 = 126 (sum of two interior opposite angle is equal to the exterior angle formed)

x = 126 - 43

x = 83 degree

Answer:

83 degrees

Step-by-step explanation:

To find this you first find the angle opposite to 126. To do this you subtract 126 from 180 as 180 degrees is a straight line, and we are looking for that missing angle.

This equals 54 degrees.

Now, 54 + 43 equals 97.

Because all interior angles of a triangle always equal 180, you can find that last angle by subtracting 97 from 180. This leaves you with 83 degrees.

Does anyone know how to do this?? steps are helpful but not necessary

Answer:

C. $\frac{2(x+16)}{x+4}$

Step-by-step explanation:

We want fg of x, so first we have to multiply f(x) times g(x).

$\frac{x+16}{x} * \frac{2x}{x+4}$

$\frac{(x+16)2x}{x(x+4)}$

$\frac{2x^{2}+32x}{x^{2}+4x}$

We can cancel out an x from every term.

$\frac{2x+32}{x+4}$

Let's rewind a little to get this into one of the answer choices.

$\frac{2(x+16)}{x+4}$ is our answer.

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when so

Ierofanga [76]

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

$4 + 3 \sqrt{x - 8} = 34$

So, solving the eq.

Subtract 4 from both sides ,

$3 \sqrt{x - 8} = 30$

Divide 3 to both sides,

$\sqrt{x - 8} = 10$

Squaring both sides,

$x - 8 = 100$

Add 8 to both sides,

$x = 108$

Students total 43430
5742 students more

43430-5742=37688

37688/2 = 18844

ANSWER
Country 1 : 18,844 students

Country 2 : 24,586 students

Explanation: By taking away the 5742 students you set them off to the side. Leaving you with a new sum. You then divide the sum by the number of countries (2). Add the remainder of the students to one of the countries.
