Solve AABC. Round your answers to the nearest hundredth, if necessary
Aloiza [94]

Answer:

C=25^{\circ},\\a\approx 10.72,\\b\approx 11.83

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees. Thus, angle C must be 180-90-65=25^{\circ}.

In any triangle, the Law of Sines is given by \frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}.

Therefore, we have:

\frac{\sin 90^{\circ}}{b}=\frac{\sin 25^{\circ}}{5},\\\\b=\frac{5\sin90^{\circ}}{\sin 25^{\circ}}=11.8310079158\approx \boxed{11.83}

\frac{a}{\sin 65^{\circ}}=\frac{5}{\sin25^{\circ}},\\a=\frac{5\sin 65^{\circ}}{\sin25^{\circ}}=10.7225346025\approx \boxed{10.72}

A clothing store paid an import tax of $32 on a shipment of $800 worth of silk scarves. The import tax rate is always the same.
bekas [8.4K]
This will be your formula:
\frac{32}{800}  =  \frac{120}{x}
cross multiply (32 times x) (120 times 800)
this is what you'll get:

A monitor measures 10.6 inches by 16.8 what is the length of the diagonal
Ludmilka [50]

Step-by-step explanation:

We will use pythagoras' Theorem for this question

{c}^{2}  =  {a}^{2}  +  {b}^{2}

where c is the longest side (in this case, the diagonal)

a and b are the 2nd and 3rd longest side (interchangeable)

given a = 10.6, b = 16.8,

{c}^{2}  =  {10.6}^{2}  +  {16.8}^{2} \\  {c}^{2}   = 112.36 + 282.24 \\  {c}^{2}  = 394.6 \\ c =  \sqrt{394.6} \\  =  \frac{ \sqrt{9865} }{5}  inches
