Answer:

A, E

Step-by-step explanation:

Remember SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Therefore, we can say:

sin 20° = LN / 8

cos 70° = LN / 8

tan 70° = MN / LN

Only the first and last options are correct.

xenn [34]

Answer:

x=1

Step-by-step explanation:

2x+8=10

subtract 8 from both sides

2x=2

x=1

32+2/3(21y-6) in factored form

artcher [175]

Answer:

14(y + 2).

Step-by-step explanation:

32 +2/3(21y - 6)

Distributing the 2/3 over the parentheses:

= 32 + 2/3*21y + 2/3 * -6

= 32 + 14y - 4

= 14y + 28

= 14(y + 2).
