A.) Similar? <u>  </u><u>YES  </u>

Why or why not? <u>  It is similar because as your can see in the picture above, it shows a large triangle and a small triangle. On the smaller triangle, the corner "G" has a degree of 67. On the larger triangle, the corner "P" has the same degree as the smaller one, therefore all the other corners have the same degree making the missing degree for "R" 34 degrees, and the missing "C" 79 degrees.  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  1.5  </u>

*I didn't know what they meant by similarity statement

B.) Similar? <u>  NO  </u>

Why or why not? <u>  The triangles are two totally different shapes, with totally different degree angles, making it totally different  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  2  </u>

*I didn't know what they meant by similarity statement

C.) Similar? <u>  NO  </u>

Why or why not? <u>  The triangles are two totally different shapes, with totally different degree angles, making it totally different  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  1.2  </u>

*I didn't know what they meant by similarity statement

D.) Similar? <u>  YES  </u>

Why or why not? <u>  They are the same shape; just with one enlarged and one decreased in size. They both have the same angle degree and everything else similar but the size of the shape.  </u>

If so, <em>*</em>similarity statement and scale factor: SF: <u>  2  </u>

*I didn't know what they meant by similarity statement

**To find the scale factor you would have to divide the big number, to the smaller number... Like for figure D, the base of the BIG triangle is 56, and the small triangle is 28. 56 ÷ 28 = 2 Making <u>2</u> the SF (Scale Factor)

Find the value of x and y <br>&lt;1=(10x) <br>&lt;2=(10y+20)<br>&lt;3 =100 ​
Rufina [12.5K]

Answer:

  1. 100
  2. 80
  3. 100
  4. 80

x = 10

y = 6

Step-by-step explanation:

We can use the vertical angle theorem to solve for most of this problem. We know that 1/3 will have the same measure and so will 4/2. We can create an equation to solve for 1 and 3.

10x = 100

x = 10

We aren't given angle 4 so we are going to have to solve that ourselves. We can create an equation knowing that 4 and 3 will create a supplementary angle.

100 + z = 180

z = 80

Now, that we have angle 4, we know that angle 2 will have the same measure because they are vertical angles. Now to find the value of y, we can take the angle measure and solve for it.

10y + 20 = 80

10y = 60

y = 6

Best of Luck!

Find u -2v given u = (-2, 5) and v = 6i -4j
Arisa [49]

Answer:

A. U - 2v = -14i +13j


Step-by-step explanation:

If u = (-2, 5) and v = 6i -4j

Then 2v = 2*(6i-4j) = 12i-8j

u-2v =  -2i +5j  - (6i -4j)

Distribute the minus sign  

        -2i +5j -6i+4j

-2i +5j

-12i + 8j

---------------

-14i +13j

What is the next number in the sequence 3, 12, 24, 33, 66
ExtremeBDS [4]
75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.
