Triangle ABC is a right triangle and sin(53o) = StartFraction 4 Over x EndFraction. Solve for x and round to the nearest whole n

zmey [24]

Answer:

cos(53°)=StartFraction y Over 5 EndFraction

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

$sin(53\°)=\frac{4}{x}$

Solve for x

$x=\frac{4}{sin(53\°)}$

$x=5$

step 2

Find the cosine of angle A

The cosine of angle A is equal to divide the adjacent side to angle A (AC) by the hypotenuse (AB)

$cos(53\°)=\frac{y}{x}$

substitute the value of x

$cos(53\°)=\frac{y}{5}$

cos(53°)=StartFraction y Over 5 EndFraction

What is an equivalent expression (m ^1/3)^ 1/5<br><br> *the fractions are powers btw*

andrezito [222]

$\bf ~\hspace{7em}\textit{rational exponents}
\\\\
a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n}
~\hspace{10em}
a^{-\frac{ n}{ m}} \implies
\cfrac{1}{a^{\frac{ n}{ m}}} \implies \cfrac{1}{\sqrt[ m]{a^ n}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\left( m^{\frac{1}{3}} \right)^{\frac{1}{5}}\implies m^{\frac{1}{3}\cdot \frac{1}{5}}\implies m^{\frac{1}{15}}\implies \sqrt[15]{m^1}\implies \sqrt[15]{m}$

Sam has 1000 to distributed among two groups equally. Later ,the first part is divided among five children and second part is di

melisa1 [442]

So basically sam split the 1000 to 2 groups so we have 1000 ÷ 2
now the first group divided the 500 (since 1000÷ 2 is 500) among five children so it would be 500 ÷ 5 which equals 100 per child and the second group divided their 500 between to boys, so you would get 500÷2 which is 250
so for group one it would be: 1000÷2÷5 which equals 100 per child and the second group is 1000÷2÷2 which equals 250 for each brother
