The measures of the angles of a triangle add up to 180 degrees.
This is true of all triangles.

You have two given angles of triangle PQR.
They are 24 degree and 100 degree.
What do those measures add up to?

What is 100 + 24? = 124


When you add the measure of the third angle to 124, you must get 180.
To find the measure of the third angle, just do 180 - 124.
What do you get?


180 - 124 = 56
That means the third angle of triangle PQR measures 56 deg.
Now we know the measures of all three angles of triangle PQR: 24, 100, 56.
Triangle RST has two angles that measure 24 deg. and 56 deg.
Since two angles of triangle PQR are congruent to two angles of triangle RST, the triangles are similar.

A line contains the points (8, 9) and (–12, –7). Using point-slope form, write the equation of the line that is parallel to the

kozerog [31]

For the answer to the question above,
The slope of the line of the line is calculated through the equation,
m = (y2 - y1) / (x2 - x1)

Using the first two points in the given,
m = (-7 - 9) / (-12 - 8) = 4/5

The line parallel to this has also a slope of 4/5. Through the point-slope form, the equation of the second line is,
y - -15 = (4/5)(x - -5)

Simplifying gives the answer of,
y = (4/5)x -11

Eliminating the fraction,
5y = 4x - 55

I hope my answer helped you.

In the design shown below, four semicircles are attached to a square whose area is 36 square centimeters. Which of the following

CaHeK987 [17]

Answer:

56.549 cm (choice 1)

Step-by-step explanation:

If the area of the square if 36 cm, then each side is 6 cm.

That means the diameter for each semi circle is also 6 cm.

Formula for a semi circle is 1/2(πr²)

We need the radius, which is half the diameter. So the radius is 6÷2= 3

Now plug in to the formula.

A= 1/2(π3²)

A= 14.137 (nearest hundredths)

Now multiply that by 4, because there are 4 semi circles

4(14.137)= 56.549 cm (nearest hundredths)

Mazyrski [523]

Answer:

x = x+1
0 = x+1
x+1 = x+1

Step-by-step explanation:

1. There will be no solution if the equation is a contradiction. Usually, it is something that can be reduced to 0 = 1.

If we choose to make our equation ...

x = x +1

Subtracting x from both sides of the equation gives ...

0 = 1

There is no value of the variable that will make this be true.

2. Something that reduces to x = c will have one solution. One such equation is ...

0 = x+1

x = -1 . . . . subtract 1 from both sides

3. Something that reduces to x = x will have an infinite number of solutions.

One such equation is ...

x+1 = x+1

Subtracting 1 from both sides gives ...

x = x . . . . true for all values of x

Find the equation for the parabola that passes through the point (-2,-4), with vertex at (3,1) and a vertical axis

Igoryamba

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (3, 1), hence

y = a(x - 3)² + 1

To find a substitute (- 2, - 4) into the equation

- 4 = a(- 2 - 3)² + 1

- 4 = 25a + 1 ( subtract 1 from both sides )

25a = - 5 ( divide both sides by 25 )

a = - $\frac{5}{25}$ = - $\frac{1}{5}$

y = - $\frac{1}{5}$ (x - 3)² + 1 ← in vertex form
