Question

Find the missing side of the triangle where cotθ=2/11​

Answer 1

Explanation:

By question ,

=> cot∅ = 2/11

=> cot∅ = 2x/11x = b/p

Pyhthagoras Theorem :-

=> h² = (2x)² + (11x)²

=> h² = 4x² + 121x²

=> h² = 125x²

=> h = √ 25 × 5 x

=> h = 5√5 x

• Sin∅ = 11/5√5
• cosec∅ = 5√5/11
• cos∅ =2/5√5
• tan∅ = 11/2
• sec∅ = 5√5/2
