If I can paint 96 sq ft in 15 minutes how long does it take to paint 1 sq ft
White raven [17]

It takes 0.15625 minutes to paint 1 square feet

<em><u>Solution:</u></em>

Given that, I can paint 96 sq ft in 15 minutes

To find: Time taken to paint 1 square feet

From given,

96 square feet is painted in 15 minutes

Let "x" be the time taken to paint 1 square feet

Then, we can say,

96 square feet = 15 minutes

1 square feet = x minutes

This forms a proportion and we can solve the sum by cross multiplying

96 \times x = 15 \times 1\\\\x = \frac{15}{96}\\\\x = 0.15625

Thus it takes 0.15625 minutes to paint 1 square feet

The cosine law
romanna [79]
\bf \textit{Law of sines}&#10;\\ \quad \\&#10;\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\&#10;-------------------------------\\\\

\bf \cfrac{sin(88^o)}{39.9}=\cfrac{sin(A)}{31}\implies \cfrac{31\cdot  sin(88^o)}{39.9}=sin(A)&#10;\\\\\\&#10;sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=sin^{-1}\left[ sin(A) \right]&#10;\\\\\\&#10;sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=\measuredangle A&#10;\\\\\\&#10;50.93841^o\approx \measuredangle A\qquad thus\qquad \measuredangle C\approx 41.0619^o
