The value of c is equal to 
Data:
- Opposite = 7
- Angle = 45 degrees
- hypothenuse = c
<h3>Trigonometric Ratio</h3>
To solve this problem, we need to use trigonometric ratio SOHCAHTOA.
Since we have opposite and hypothenuse value, we can use sine angle for this.

Let's substitute the values into the formula

The value of c is equal to
