A Pamela le encomendaron determinar la cantidad
de cerca necesaria para cercar un terreno pero
Solo le indicaron las
coordenadas de las esquinas
del terreno las cuales Son: 10,6), (311)
. (9, 10),(10.3)
Y (2.0) ¿cuantos metros de cerca debe solicitar ?

it should be a and d. lmk if i'm wrong xd

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

b. 2 and 4

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
