Hi there!
In order to find x, we'll need to create an expression. We know that angle x would be 180 - angle ABC - y. Since we know that angle ABC is equal to 30, we can substitute that in. This gives us 180 - 30 - y. Lastly, we can simplify to get our expression. The expression is 150 - y. The answer is the first option.
Hope this helps!! :)

The sum of your data set is 23.8333333333.All you have to do is add them all together and then divide by 6, which is the number of numbers there are.
8+13+17+26+32+47=143
143/6+23.8333333333
Since <span><span>−64</span><span>-64</span></span> does not contain the variable to solve for, move it to the right side of the equation by adding <span>6464</span> to both sides.<span><span><span>x2</span>=64</span><span><span>x2</span>=64</span></span>Take the square root of both sides of the equation to eliminate the exponent on the left side.<span><span>x=<span>±<span>√64</span></span></span><span>x=<span>±64</span></span></span>The complete solution is the result of both the positive and negative portions of the solution.
<span>x=8,<span>−<span>8</span></span></span>
