Using the law of sines, find the solutions for the missing inputs.

SashulF [63]

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) }$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\frac{12}{ \sin(38) } = \frac{a}{ \sin(57) }$
$180 - (85 + 38) = 57$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\sin(85) \times \frac{12}{ \sin(38) } = b$
$\sin(57) \times \frac{12}{ \sin(38) } = a$
sorry for the order of steps

So far you have completed 80% of the problems for your math exam. Your exam

zmey [24]

Answer:

Problems left to complete = 9

Step-by-step explanation:

Given that:

Number of problems on the test = 45

Percent of completed problems = 80%

Number of completed problems = $\frac{80}{100}*45$

Number of completed problems = 0.8 * 45 = 36

Problems left to complete = 45 - 36

Problems left = 9

Hence,

Problems left to complete = 9

Which choice correctly shows the solution(s) of the equation x2 = 121?

kvasek [131]

Hello from MrBillDoesMath!

Answer:

Choice D, x = +\ sqrt(121)

Discussion:

x^2 = 121 => take square roots of both sides

x = +\- sqrt(121) => as sqrt(121) = +\- 11

x = +\- 11

The closest answer is D as it includes both values of x, unlike choices A and B which include a single value of the square root

Thank you,

MrB
