The price of petrol increased from Rs 48 to rs 53.76.

mylen [45]

Answer:

12%

Step-by-step explanation:

As per the provided information in the given question, we have :

Original price of petrol = Rs. 48
New price of petrol = Rs. 53.76

We are asked to calculate,

Percentage increase

As we know that,

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{Price \; increase}{Original \; price} \times 100 \Bigg ) \; \%}} \\$

→ Price increase = New price - Original price

→ Price increase = Rs. ( 53.76 - 48 )

→ Price increase = Rs. 5.76

Substituting values,

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{5.76}{48} \times 100 \Bigg ) \; \%}} \\$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{4800} \times 100 \Bigg ) \; \%}} \\$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{57600}{4800} \Bigg ) \; \%}} \\$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{48} \Bigg ) \; \%}} \\$

$\\ \longrightarrow \bf{\quad\underline { \% \; increase = 12\; \%}} \\$

Find the missing side. round to the nearest tenth

barxatty [35]

So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!
