Remark

First of all, we had best correct the labeling. The adjacent is the side making up the unknown angle, and the opposite is the side not making up the given angle (in this case, x)

So you have mixed up the opposite and the adjacent. You need to switch them.

Step Two (Bottom Diagram)

Sin(x) = opposite / hypotenuse

Sin(x) = 12 / 18

Sin(x) = 2/3

Sin(x) = 0.6666666666

x = sin-1(0.66666666)

x = 41.18103

Problem One (Top One)

Sin(x) = opp/hypotenuse

Sin(x) = 4/5

Sin(x) = 0.8

x = sin-1(0.8)

x = 53.13 Answer <<<<<

PLEASE HELP ASAP!!!!
Naily [24]

Answer:

2

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

let

log_{2} 8 = n ⇒ 8 = 2^{n} , that is

2³ = 2^{n} ( equate exponents )

n = 3

and let

log_{3} ( \frac{1}{3} ) = n ⇒ \frac{1}{3} = 3^{n} , that is

3^{-1} = 3^{n} ( equate exponents )

n = - 1

then

log_{2} 8 + log_{3} (\frac{1}{3} )

= 3 + (- 1)

= 3 - 1

= 2

7/10 divide by 1/5 - 4/3 x 10/11
Karolina [17]

Answer:

(-340)/231

Step-by-step explanation:

Simplify the following:

((-34)/33)/(7/10)

Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:

(-34×10)/(33×7)

33×7 = 231:

(-34×10)/231

-34×10 = -340:

Answer:  (-340)/231
