Sin 33°= 7/x<br> A. 5.9<br> B. 12.9<br> C. 10.8<br> D. 8.3
DanielleElmas [232]

Answer:

B

Step-by-step explanation:

The equation to solve is:

Sin(33)=\frac{7}{x}

Sin 33 has a value in the calculator. We simply cross multiply and do algebra and solve:

Sin(33)=\frac{7}{x}\\Sin(33)*x=7\\x=\frac{7}{Sin(33)}\\x=12.85

Rounding to 1 decimal place, we have:

12.85 = 12.9

Answer choice B is right.

Mila [183]

Answer:

3/4 or 0.75 decimal

Step-by-step explanation:

Simplify the following:

(2/3)/(8/9)

Hint: | Write (2/3)/(8/9) as a single fraction.

Multiply the numerator by the reciprocal of the denominator, (2/3)/(8/9) = 2/3×9/8:

(2×9)/(3×8)

Hint: | In (2×9)/(3×8), divide 9 in the numerator by 3 in the denominator.

9/3 = (3×3)/3 = 3:

(2×3)/8

Hint: | In (2×3)/8, divide 8 in the denominator by 2 in the numerator.

2/8 = 2/(2×4) = 1/4:

Answer: 3/4
