Solve any two sub questions from the following :
`square` PQRS is a quadrilateral in which `manglep=80^@,mangleQ=70^@` and `mangleR=mangleS` Find the measures of `angleR` and `angleS`

Explanation

To find the measures of angles R and S in the quadrilateral PQRS, we will follow these steps:

### Step 1: Understand the properties of a quadrilateral
The sum of all interior angles in a quadrilateral is always 360 degrees.

### Step 2: Write the equation for the angles
Given:
- Measure of angle P = 80 degrees
