Question 1/4 Medium Mathematics Trigonometric Functions Angles Class 11 Level 69

\(72^\circ 30'\) को दशमलव डिग्री में बदलने पर क्या मिलेगा?

What is \(72^\circ 30'\) in decimal degrees?

Explanation opens after your attempt
Correct Answer

B. \(72.5^\circ\)

Step 1

Concept

\(30'=\frac{30}{60}^\circ=0.5^\circ\), so the value is \(72.5^\circ\). Do not write minutes directly as decimals.

Step 2

Why this answer is correct

The correct answer is B. \(72.5^\circ\). \(30'=\frac{30}{60}^\circ=0.5^\circ\), so the value is \(72.5^\circ\). Do not write minutes directly as decimals.

Step 3

Exam Tip

\(30'=\frac{30}{60}^\circ=0.5^\circ\) इसलिए मान \(72.5^\circ\) है। मिनट को दशमलव में सीधे न लिखें।

Question 3/4 Medium Mathematics Trigonometric Functions Angles Class 11 Level 67

\(18^\circ 30'\) को दशमलव डिग्री में बदलने पर क्या मिलेगा?

What is \(18^\circ 30'\) in decimal degrees?

Explanation opens after your attempt
Correct Answer

B. \(18.5^\circ\)

Step 1

Concept

\(30'=\frac{30}{60}^\circ=0.5^\circ\) so the total is \(18.5^\circ\). Divide minutes by (60) to convert them into degrees.

Step 2

Why this answer is correct

The correct answer is B. \(18.5^\circ\). \(30'=\frac{30}{60}^\circ=0.5^\circ\) so the total is \(18.5^\circ\). Divide minutes by (60) to convert them into degrees.

Step 3

Exam Tip

\(30'=\frac{30}{60}^\circ=0.5^\circ\) इसलिए कुल \(18.5^\circ\) है। मिनट को डिग्री में बदलने के लिए (60) से भाग दें।
