`Delta` PQR is right angled at Q. If tanP = 24/7, then what is the value of cosR ?

Options

A. `25//7`
B. `24//25`
C. `24//7`
D. `7//24`

Explanation

To solve the problem, we need to find the value of cos R in triangle PQR, which is right-angled at Q. We are given that tan P = 24/7. Let's break down the solution step by step.

### Step 1: Understand the triangle
In triangle PQR, angle Q is 90 degrees. We know that:
- tan P = opposite side (QR) / adjacent side (PQ)

### Step 2: Assign values based on tan P
From the given information:
