Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.

Answer: y = 9x
Step-by-step explanation:
Li needs to use 9 beads for each inch of necklace.
X = Length of Necklace
Y = Number of beads needed
y = 9x
For instance, assuming a necklace is 8 inches long, how many beads will be needed;
= 9x
= 9 * 8
= 72 beads
D. Translation and dilation, no
You know it’s a translation because first it’s not in the same spot and second it is an answer choice in all the answer
You know it’s not a reflection because the shape looks the same and every point faces the same direction
So that is means it’s a dilation.
You also know that it’s a dilation because there is a size difference between the two.
Lastly because of the size difference, they aren’t congruent because congruent means the same and they aren’t the same size
