The answer is in the thousands group. Its the way they word the problem that complicates it. 913,256 256 being the ones group 913 being the thousands group. So the name of the period with 913, is the thousands group

Find the measure of the missing angle.<br> a<br> 50°
xeze [42]

Answer:

a = 40°

Step-by-step explanation:

I. When total angle is 180 or half of circle

Find a or missing angle by

180 = 50 + 90 + x

180 - 140 = x

x = 40º

That makes a is 40º

Hope that help :)

How do I do these? I don’t understand how my teacher is teaching it so can someone explain
Mamont248 [21]

Here's some guidelines to help you:

For 1, 4, 5, and 6, they are 30-60-90 triangles. What's that you may ask? Well, it means that the sides have a predetermined length when one side is given. In #1 for example, you have a side of 11sqrt3, this means that "n" is 11 because in a 30-60-90 triangle, the longer side is the sqrt3 times the length of the shorter side. So to get the shorter side, we divide by sqrt3 to get 11. "m", or the hypotenuse, can be determined by taking twice the length of the shorter side. Since we figured out earlier that the shorter side is 11, 11 times 2 is 22. So the answer for #1 is n=11, m=22.

For 2 and 3, they are 45-45-90 triangles, triangles where the two lengths are the same and the hypotenuse is either leg length times sqrt2. In problem #2 for example, "y" must be 17 because one leg length is 17. "x", or the hypotenuse, is equal to 17sqrt(2) because 17 times sqrt(2).

You can apply all these rules to the other 4 problems I didn't explain.

Hope this long explanation clears your doubts!

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )
Anna007 [38]

Answer:

y=2x+3

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

y-y_1=m(x-x_1)

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

y-7=2(x-2)

Solve for y. Distribute the right:

y-7=2x-4

Add 7 to both sides. Hence, our equation is:

y=2x+3
