First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: $$\sqrt{\frac{ {72x}^{16} }{ {50x}^{{{36} }}}} = \frac{ { \sqrt{72}x}^{ {16}^{ (\frac{1}{2}) } } }{ { \sqrt{50} x}^ {{36}^{ (\frac{1}{2}) } }}$$multiply exponents per exponent rules to get: $$\frac{ { \sqrt{72}x}^{8} }{ { \sqrt{50}x}^{18} }$$remember you subtract exponents from the denominator and add exponents in the numerator so: $$\sqrt{ \frac{72}{ 50}} \times ( {x}^{(8 - 18) } ) = \sqrt{ \frac{36}{25} } \times ( {x}^{ - 10} )$$simplify further: $$\frac{6}{5} {x}^{ - 10} = \frac{6}{5 {x}^{10} }$$so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results. 26.06.2019 21:20

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
