arccos(x)=(79)/(9sqrt(70))

arccos (x) = \frac{79}{9 70}

x = cos (\frac{79 70}{630})

Solution steps

arccos (x) = \frac{79}{9 70}

Simplify

\frac{79}{9 70} : \frac{79 70}{630}

\frac{79}{9 70}

Multiply by the conjugate

\frac{70}{70}

= \frac{79 70}{9 70 70}

97070 = 630

97070

Apply radical rule:

a a = a

7070 = 70

= 9 \cdot 70

Multiply the numbers:

9 \cdot 70 = 630

= 630

= \frac{79 70}{630}

arccos (x) = \frac{79 70}{630}

Apply trig inverse properties

arccos (x) = \frac{79 70}{630}

arccos (x) = a \Rightarrow x = cos (a)

x = cos (\frac{79 70}{630})

x = cos (\frac{79 70}{630})
