82.90598 \dots

Solution steps

9 5^{2} + 57.7 3^{2} - 2 \cdot 95 \cdot 57.73 sin (3 0^{\circ})

= 9 5^{2} + (\frac{5773}{100})^{2} - 2 \cdot 95 \cdot \frac{5773}{100} sin (3 0^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

= \frac{1}{2}

= 9 5^{2} + (\frac{5773}{100})^{2} - 2 \cdot 95 \cdot \frac{5773}{100} \cdot \frac{1}{2}

Simplify

9 5^{2} + (\frac{5773}{100})^{2} - 2 \cdot 95 \cdot \frac{5773}{100} \cdot \frac{1}{2} : \frac{68734029}{100}

9 5^{2} + (\frac{5773}{100})^{2} - 2 \cdot 95 \cdot \frac{5773}{100} \cdot \frac{1}{2}

(\frac{5773}{100})^{2} = \frac{577 3 ^{2}}{10 0 ^{2}}

(\frac{5773}{100})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{577 3 ^{2}}{10 0 ^{2}}

2 \cdot 95 \cdot \frac{5773}{100} \cdot \frac{1}{2} = \frac{109687}{20}

2 \cdot 95 \cdot \frac{5773}{100} \cdot \frac{1}{2}

Multiply fractions:

a \cdot \frac{b}{c} \cdot \frac{d}{e} = \frac{a \cdot b \cdot d}{c \cdot e}

= \frac{5773 \cdot 1 \cdot 2 \cdot 95}{100 \cdot 2}

Cancel the common factor:

2

= \frac{5773 \cdot 1 \cdot 95}{100}

Multiply the numbers:

5773 \cdot 1 \cdot 95 = 548435

= \frac{548435}{100}

Cancel the common factor:

5

= \frac{109687}{20}

= 9 5^{2} + \frac{577 3 ^{2}}{10 0 ^{2}} - \frac{109687}{20}

9 5^{2} = 9025

9 5^{2}

9 5^{2} = 9025

= 9025

\frac{577 3 ^{2}}{10 0 ^{2}} = \frac{33327529}{10000}

\frac{577 3 ^{2}}{10 0 ^{2}}

577 3^{2} = 33327529

= \frac{33327529}{10 0 ^{2}}

10 0^{2} = 10000

= \frac{33327529}{10000}

= 9025 + \frac{33327529}{10000} - \frac{109687}{20}

Join

9025 + \frac{33327529}{10000} - \frac{109687}{20} : \frac{68734029}{10000}

9025 + \frac{33327529}{10000} - \frac{109687}{20}

Convert element to fraction:

9025 = \frac{9025}{1}

= \frac{9025}{1} + \frac{33327529}{10000} - \frac{109687}{20}

Adjust Fractions based on the LCM

Multiply each numerator by the same amount needed to multiply its

corresponding denominator to turn it into the LCM

10000

For

\frac{9025}{1} :

multiply the denominator and numerator by

10000

\frac{9025}{1} = \frac{9025 \cdot 10000}{1 \cdot 10000} = \frac{90250000}{10000}

For

\frac{109687}{20} :

multiply the denominator and numerator by

500

\frac{109687}{20} = \frac{109687 \cdot 500}{20 \cdot 500} = \frac{54843500}{10000}

= \frac{90250000}{10000} + \frac{33327529}{10000} - \frac{54843500}{10000}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{90250000 + 33327529 - 54843500}{10000}

Add/Subtract the numbers:

90250000 + 33327529 - 54843500 = 68734029

= \frac{68734029}{10000}

= \frac{68734029}{10000}
