Answer:

Three-fifths

Step-by-step explanation:

Sin(E) = opposite/hypotenuse

DE is the base/adjacent, EF is the hupotenuse

DF if the opposite/perpendicular use pythagoras theorem to find DF:

10² = DF² + 8²

100 = DF² + 64

DF² = 36

DF = 6

Sin(E) = DF/EF

= 6/10 = 3/5 = 0.6

maria [59]

Answer:

e^2 -7 = x

Step-by-step explanation:

2=ln(x+7)

Raise each side to the base of e

e^2 = e^ln (x+7)

The e^ln cancel

e^2 = x+7

Subtract 7 from each side

e^2 -7 = x +7-7

e^2 -7 = x

2/3(x+6)=-18 I need the answer help me!!
iragen [17]

Answer:

x = -33

Step-by-step explanation:

2/3(x+6) = -18

multiply (x+6) by 2/3

2/3x + 4 = -18

subtract 4 from both sides

2/3x + 4 - 4 = -18 - 4

2/3x = -22

multiply by 3/2

2/3 x 3/2 x = -22 x 3/2

x = -33
