Hi, I want to calculate the third side(hypotenuse) of right angle triangle when user gives the length of 2 side (height and base. when calculate button is clicked the result does not want to display in the third input box (h).

i could not figure it out what is wrong with my code.

## Round 1

#### solution 1: right angle traingle's side calculator

```
<form action="", name = "formclac">
<ul>
<li> Base of triangle (b)* <input type="number" name = "base">
</li>
<li>Perpencidular (p)* <input type="number" name = "perp"></li>
<li id = "center"><input type="button" value ="calculate" onClick
="thirdside()"></li>
<li id = "result">hypotenous (h) <input type="number" name ="hypot">
</li>
</ul>
</form>
<script>
function thirdside() {
var p, b ,h
b = document.formcalc.base.value;
p = document.formcalc.perp.value;
h = math.sqrt(math.pow(b,2)+ math.pow(p,2));
document.formcalc.hypot.value = h;
}
</script>
```
