18 if it’s not, then 21. I did ratios i long time ago so i don’t fully remember them.
The odds are one in three hundred twelve.

We know that vertically opposite angles are equal.
So, k = 131° [Vertically opposite angles]
and g = 43° [Vertically opposite angles]
We know that linear pair of angles are supplementary (180°).
So, h + 43° = 180° [Linear pair of angles]
=> h = 180° - 43°
=> h = 137°
and m + 131° = 180° [Linear pair of angles]
=> m = 180° - 131°
=> m = 49°
So, this is how we do it O w O<span><span>x = <span>−1</span></span>;<span>y = <span><span>3x</span>+1</span></span></span>Step: Solve <span>x = <span>−1 </span></span>for x:Step: Substitute <span>−1 </span>for x in <span><span>y = <span><span>3x</span>+1</span></span>:</span><span>y = <span><span>3x</span>+1</span></span><span>y = <span><span><span>(3)</span><span>(<span>−1</span>)</span></span>+1</span></span><span>y = <span>−2</span></span>(Simplify both sides of the equation)Answer:<span><span>x=<span>−<span><span>1<span> and </span></span>y</span></span></span>=<span>−<span>2
Hope I helped! :3</span></span></span>
