Answer:

A. 4

Step-by-step explanation:

Use the law of sines to solve:

\frac{sin 90}{8}=\frac{sin30}{x}  \\x=8sin30\\x=4

Alternate method: use properties of 30-60-90 triangle:

If the hypotenuse of a 30-60-90 triangle has a length of x, then the shortest leg has a measure of \frac{x}{2}.

Substitute x and you will get 4 as your answer.

A sales man is paid a basic wage of $225 per week. In addition he is paid a commission of 3% on the value of goods he sells abov
mihalych1998 [28]

Answer:

Commission = $375

Total earnings = $600

Step-by-step explanation:

He gets 3% of any sale he makes above %5500 which means his commission received on this sale is;

= 3% * $12500

= \frac{3}{100} * $12500

= 3* 125

= $375

This means his total earnings for the week will be the basic wage plus his commission

$225 + $375

= $600

Find the length of Arc YWV, if line XZ=12 meters. (Round to the nearest hundredth)
Oksana_A [137]

Answer:

53.62 m

Step-by-step explanation:

Length of arc = θ/360 × 2πr

r = XZ = 12 m

m<XYZ = 180 - 108 = 72° (angles on a straight line)

θ = 85° + 72° + 108° = 265°

Length of arc YWV = 256/360 × 2 × π × 12

= 53.6165146 ≈ 53.62 m (nearest hundredth)

Factor out the coefficient 1/2d+6
Ratling [72]
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:

1/2d + 6 = 1/2 (d + 3)

Hope this helps!
