Which function forms a geometric sequence when x = 1, 2, 3, ...? f (X) = 8 x minus 9
f (x) = negative 2 (three-fourths) Superscript x
f (x) = two-thirds x Superscript 5
f (x) = 6 minus StartFraction 4 Over x EndFraction

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

i think the length is 12 and the width is 17
