Answer:
None of them
Step-by-step explanation:
Because 30+135+45 add up to 210 then if you add 30, or 45 degrees it will be more than 180 degrees. If you subtract -15 from 210 you will get 195 which is still not right. So the best answer is none of the above
Hope this helps
Answer:
Parallel
Step-by-step explanation:
The slopes are the same, they are both 0.
Answer:
U is the midpoint of a segment in the diagram
Answer: She will need 36 yards of material.
Step-by-step explanation:
16 × 2¹/₄ can be done different ways,
First multiply ¹/₄ times 16. that is the same as dividing 16/4 = 4
Then multiply 2 times 16 2×16 = 32
Add 32 + 4 = 36
Another way is to change 2¹/₄ to an improper fraction and multiply
⁹/₄ × 16
16
<u> ×9</u>
54
<u> +9 </u>
144
144/4 = 36

Answer:
From the given graph:
the coordinates of triangle RST are;
R= (2, 1),
S= (2,-2),
T= (-1,-2)
Given: Scale factor = 
and center of dilation at (2,2)
The mapping rule for the dilation applied to the triangle as shown below:
; where k represents the scale factor i.e, 
or we can write it as ;
For R=(2, 1)
The image R' = 
⇒ R'= 
Similarly for S= (2, -2) and T= (-1,-2)
therefore, the image of S'= 
⇒ S'= 
The image of T' =
⇒T' = 
Now, labelling the image of triangle R'S'T' as shown in the figure given below
