astra-53 [7]

Answer:

7.0 mi

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle C

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

A+B+C=180^o

substitute the given values

42^o+64^o+C=180^o\\C=180^o-106^o=74^o

step 2

Find the measure of a

Applying the law of sines

\frac{c}{sin(C)}=\frac{a}{sin(A)}

substitute the given values

\frac{10}{sin(74^o)}=\frac{a}{sin(42^o)}

solve for a

a=\frac{10}{sin(74^o)}sin(42^o)\\a=7.0\ mi

Solve for all possible values of x. square root of the quantity x plus 6 end quantity plus 5 equals 17
Georgia [21]

Answer:

x=138

Step-by-step explanation:

So we have the equation:

\sqrt{x+6}+5=17

First, let's determine the domain restrictions. Recall that the radicand cannot be negative. In other words, it must be greater than or positive than 0. Thus:

x+6\geq 0

Subtract 6 from both sides:

x\geq -6

What this means is that our solutions must be greater than or equal to -6. If not, we ignore them.

So, let's subtract 5 from both sides from the original equation:

\sqrt{x+6}=12

Square both sides:

x+6=144

Subtract 6 from both sides:

x=138

138 is greater than -6, so 138 is a solution and is the only solution.

And we're done!
