Question

find the value of x in each of the following 1. 3x=cot30degree + cot 60degree by 1+cot 30 degree.cot60 degree
​

Answer 1

Answer:

x=2/3(3)^1/2

Step-by-step explanation:

3x= cot30°+cot60°/(1+cot30°+cot60°)

3x= (3)^1/2 + (1/3)^1/2/{1+(3)^1/2×(1/3)^1/2}

3x= 3+1/2(3)^1/2

3x=4/2(3)^1/2

3x=2/(3)^1/2

x=2/3(3)^1/2
