Answer:
18.61
Step-by-step explanation:
Principle = £4500
Time = 6yrs
Rate = n%
Simple interest = £5025
n = ?
We know,
SI =PTR/100
£5025 = £4500*6*n/100
£502500 = £27000*n
n = 18.61

Answer:
27
Step-by-step explanation:
note that tanx cotx = tanx ×
= 1
Given
tanx - cotx = 5 ( square both sides )
(tanx - cotx)² = 5² = 25 ← expand left side using FOIL
tan²x - 2tanxcotx + cot²x = 25
tan²x - 2 + cot²x = 25 ( add 2 to both sides )
tan²x + cot²x = 27
