1) By the inscribed angle theorem, 
2) By the inscribed angle theorem, arc RT measures twice 63 degrees, or 126 degrees.
Answer:
Scale factor, K = -1/4
Step-by-step explanation:
Dilation of any image changes its size and the shape remains same.
The scale factor is the ratio of dilated image to original image.
Dilation rule: (x, y) → (kx, ky), where k is the scale factor.
It means k = x₂/x₁ or y₂/y₁
K = -5/20 = -1/4 or K = -4/16 = -1/4.
<u>The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.</u>
Hence the scale factor is K = -1/4.
Answer:
0.25 miles
Step-by-step explanation:
assuming that she keeps a constant Velocity/ speed,
find the speed she intends to run with, ie total distance/time
find the distance she travels in two minutes, ie speed multiplied by time.
2/3 of a minute is longer than 1/3 of a minute
Change the common denominator so 3/4 ---> 9/12
3/4 and 9/12 are equal
Hope this helps!!!
