# NCERT Solutions Class 10 Maths Chapter 8 Exercise 8.3 Introduction to Trigonometry

NCERT solutions for class 10 maths chapter 8 exercise 8.3 Introduction to Trigonometry elucidates on the trigonometric ratios of complementary angles. Two angles are said to be complementary if their sum equals 90°. We know that in a right-angled triangle one angle measures 90° while the sum of the other two will also be 90° according to the angle sum property. This is the concept that is used to derive the formulas used for this exercise. Most of these questions are proof-based. Hence students need to study the theory carefully so as to provide detailed answers to these sums. NCERT solutions class 10 maths chapter 8 exercise 8.3 has 7 questions that combine the complementary angles with the topics taught in previous sections.

The problems range from evaluating expressions, finding values, and verification sums. In order to solve these sums seamlessly, it is important to ensure that kids have a good conceptual knowledge of the subject matter that was previously introduced. Additionally, understanding the interchangeability of the trigonometric ratios depending on the angles is also crucial. The detailed explanations of class 10 maths NCERT solutions chapter 8 exercise 8.3 Introduction to Trigonometry is given below in PDF format and is free to download.

## NCERT Solutions Class 10 Maths Chapter 8 Exercise 8.3 Tips

NCERT solutions class 10 maths chapter 8 exercise 8.3 Introduction to Trigonometry can be mastered by going through the NCERT textbook and practicing the solved examples. It is essential to understand how values in trigonometry can impact solutions. One of the best ways to remember values is by preparing a chart and reading it every day along with the formulas. In order to solve this exercise, students need to have a stronghold on the theoretical concepts explained in the NCERT textbook.

NCERT solutions class 10 maths chapter 8 exercise 8.3 shows that if sin A is given by perpendicular/ hypotenuse then sin (90 - A) equals base/ hypotenuse. Additionally, cos A is also base/ hypotenuse. This means that sin (90 - A) = cos A. Similarly, the formulas of the complementary angles for the remaining trigonometric ratios have been derived.
