The answer is false every circle does not have the same radii.
Answer:
x=13
Step-by-step explanation:
Answer:
ST & TS are congruent
RST and UTS are congruent
Step-by-step explanation:
The question is not properly presented; however, I've added an attachment to give a clear picture of the question.
Required
State the property that justifies:

Triangles 
From the question, we have that:


In plane geometry, the length of ST is still the same as the length of TS.
This implies that:
because ST is congruent to TS
Moving further to determine the relationship between triangles 
Comparing both triangles:
They have a similar side ST and TS because 
And we also have that: 
So, we can conclude that:
because they are congruent
100-16=84. 84/2=42. 42+16=58. The lengths are 42cm and 58cm.
Answer:
-4
Step-by-step explanation:
Use the given value of f(1) to find f(2):
f(2) = f(1) · (-1/2) = (-16)(-1/2) = 8
Now, we can find f(3) using f(2):
f(3) = f(2) · (-1/2) = (8)(-1/2)
f(3) = -4
