Answer:

49.2°

Step-by-step explanation:

To solve for x you'll need to find the cosine of x°.

To find the cosine you will need to divide the adjacent side to it by the hypotenuse.

cos x°= \frac{17}{26}

Using a calculator to solve you'll get that x ≈ 49.2°

Hi.... your answer is below:

\left( 4.x^{a} \right)^{b}=\dfrac{256}{x^{8}}\rightarrow 4^{b}x^{ab}=256x^{-8}\rightarrow 2^{2b}.\,x^{ab}=2^{8}.\,x^{-8}\rightarrow\\ \text{by comparison}\\ 2^{2b}=2^{8}\rightarrow 2b=8\rightarrow \boxed{b=4}\\ x^{ab}=x^{-8}\rightarrow x^{4a}=x^{-8}\rightarrow 4a=-8\rightarrow \boxed{a=-2}

Thanks....
