112 is what it should be set less than or equal to because she needs at least this much money for the dress. So 112 should be equal to or less than the amount she earns total. 112≤? On the other side you need to put 40 because this is what she already has. You need to add 40 to 9x, x being the amount of hours she works. so your inequality is 112 ≤ 9x +40. 
From there subtract 40 on both sides and then divide by 9. Your answer should be 8 hours.

Please help me <br> I have to solve the triangle with the law of sines
Nikitich [7]

Check the picture below.

and since a triangle has a sum of 180° for all interior angles.

A = 180 - 39.34 - 25

A = 115.66

\bf \cfrac{sin(25^o)}{44}=\cfrac{sin(A)}{a}\implies \cfrac{sin(25^o)}{44}=\cfrac{sin(115.66^o)}{a} \\\\\\ a\cdot sin(25^o)=44\cdot sin(115.66^o)\implies a=\cfrac{44\cdot sin(115.66^o)}{sin(25^o)} \\\\\\ a\approx 93.8452\implies \stackrel{\textit{rounded up}}{a = 93.85}

make sure your calculator is in Degree mode.

Find m∠1 if m∠2=73°, m∠3=107°, m∠4=92°. Justify your response!
a_sh-v [17]

Answer:

m∠1 = 92°

Step-by-step explanation:

∠2 corresponds to the supplement of ∠3 if (and only if) lines a and b are parallel. We find that

m∠2 + m∠3 = 73° +107° = 180°

so, the angles are supplementary and lines a and b are parallel.

Angles 4 and 1 are corresponding angles where the line d crosses the parallel lines a and b, so are congruent.

m∠1 = m∠4 = 92°
