# Javascript program to enter the two angles of a triangle and find the third angle

ADVERTISEMENTS

__Javascript __program to enter the two angles of a triangle and find the third angle. There are you will learn how to find the third angle of a triangle in javascript language.

**Base Knowledge:**

*a**° + b° + c° = 180°*

**Formula:**

*c**°** = 180**°** - (a**°** + b**°**)*

Let us understand this example through Javascript program:

```
/* Javascript program to find all angles of a triangle if two angles are given */
<script type="text/javascript">
var p, q, r;
// p, q, and r is all angles of the triangle
p = 45;
q = 85;
// Compute third angle
r = 180 - (p + q);
document.write("Third angle of the triangle = " + r);
</script>
```

**Output Screen:**

Third angle of the triangle = 50
