Important Questions for Class 10 Maths Chapter 8 Introduction to Trigonometry Introduction to Trigonometry Class 10 Important Questions Very Short Answer (1 Mark) Question 1. If tan θ + cot θ = 5, find the value of tan2θ + cotθ. (2012) Solution: tan θ + cot θ = 5 … [Given tan 2θ + cot 2θ + 2 tan θ cot θ = 25 … [Squaring both sides tan 2θ + cot 2θ + 2 = 25 ∴ tan 2θ + cot 2θ = 23 Question 2. If sec 2A = cosec (A – 27°) where 2A is an acute angle, find the measure of ∠A. (2012, 2017D) Solution: sec 2A = cosec (A – 27°) cosec(90° – 2A) = cosec(A – 27°) …[∵ sec θ = cosec (90° – θ) 90° – 2A = A – 27° 90° + 27° = 2A + A ⇒ 3A = 117° ∴ ∠A = \(\frac\) = 1.41, if required) (2014OD) Solution: Filed Under:

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 The problems range from evaluating expressions, finding values, and verification sums.
