Question

can you solve this questions​

Answer 1

Answer:

answer of question 11 =

sec30°=2/√3

tan 60°=√3

sin 45°=1/√2

coesc 45°=√2

cos 30°=√3/2

cot 60°=1/√3

now put the values in given equation

sec30°tan60°+sin45°cosec45°+cos30°cot60°=7/2

2/√3×√3+1/√2×√2+√3/2×1/√3=7/2

7/2=7/2

hence proved .

I hope this will help you .
