If the measure of \angle∠4 is 68 degrees,, find the measure of \angle2∠2 in degrees.

Answers

Hi, there! I'd love to help you out!

We know complementary angles add up to 90 degrees.

Let's say our first angle is x:

x = first angle

It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:

x = first angle

x + 68 = second angle

Now add the two and set it equal to 90 degrees:

x + x + 68 = 90

2x + 68 = 90

-68 -68

2x = 22

/2 /2

x = 11 first angle

x + 68 = 11 +68 = 79 degrees second angle

Answer:

1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)

Step-by-step explanation:

A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.

B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.

6x6x10=360 you have to multiply all sides
To answer this you must split the shape into 2 other shapes at least this how I do it

First do the square 6x6=36
Then do the 2 triangles
3x10=30
(Normally you would divide the answer by 2 since a triangle is half of a square but since there is another triangle this is not needed)
After that add the area of the square to the area of the 2 triangles and your answer is 66

What is 4x + 10 = -26

Answers

Answer:

x = -9

Step-by-step explanation:

I'm assuming you're looking for X.

So first, you'll want to subtract 10 from both sides of the equation.

4x + 10 = -26

    - 10  |  -10

4x = -36

Then from there, you'll want to divide by 4. This allows us to get x by itself.

4x = -36

/4  |   /4

x = -9

The value of 'x' is -9 in the given equation.

To solve the equation 4x + 10 = -26, follow these steps:

Step 1: Isolate the variable term by subtracting 10 from both sides of the equation.

4x + 10 - 10 = -26 - 10

4x = -36

Step 2: Solve for 'x' by dividing both sides of the equation by 4.

4x / 4 = -36 / 4

x = -9

So, the value of 'x' is -9.
