I’m pretty sure you are supposed to use the law of sine, which states A/sin(a)=B/sin(b)=C/sin(c), where A is the side opposite of angle A. Number 4 would be28/sin37=x/sin49, solving for x. I do not have a calculator with me but I hope this helps

The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2

47  = [ (360 - x) - x ] / 2

94 = 360 - 2x

x = 133 degrees of the arc

Given :-

  • (9^{2} )^{-1/3}

To Find :-

  • To solve the expression .

Solution :-

Given expression to us is ,

(9^{2} )^{-1/3}

We know that ,

9 = 3^2

So our expression becomes ,

\{ (3^2)^2\}^{\frac{-1}{3}}

And , (a^m)^n =a^{mn} . Using this ,

(3^4)^{\frac{-1}{3}}

Again using the same law ,

3^{\frac{-4}{3}}

We know that , a^{-m}=\frac{1}{a^m} . Therefore ,

(3^{-4})^{\frac{1}{3}}

\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}

\\ \dfrac{1}{\sqrt[3]{3^4}}

Simplify ,

\dfrac{1}{3\sqrt[3]{3}}

This is the simplified expression.

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>.</em>
