If cente ris (h,k) and radius is r then
equatn is (x-h)^2+(y-k)^2=r^2
so
center (5,4)
r=2
h=5
k=4
(x-5)^2+(y-4)^2=2^2
(x-5)^2+(y-4)^2=4
first option
Answer:
K = 42
Step-by-step explanation:
K/2 = 21
2* k/2 =2*21
k=42
The measure of angle R is 50° because x=3.
You do cross multiplication so multiply 29 by 38 and then divide it by 78 which gives you answer of 14.128 cm
