If cos alpha/cos bita=m and cos alpha/sin bita =n then show that m^2+n

1.	If cos alpha/cos bita=m and cos alpha/sin bita =n then show that m^2+n^2×cos^2bita=cot^2thita
Answer» Step-by-step explanation: The ratio of their atomic masses: Carbon dioxide, (CO 2 )=C:O=12:32=3:8 Calcium oxide, (CAO)=Ca:O=40:16=5:2 Sodium CHLORIDE, (NaCl)=NaCl=23:35.5 Magnesium sulphide, (MgS)=24:32=3:4 Hence, the CORRECT match is option A.

If cos alpha/cos bita=m and cos alpha/sin bita =n then show that m^2+n^2×cos^2bita=cot^2thita

Answer»

Step-by-step explanation:

The ratio of their atomic masses:

Carbon dioxide, (CO

)=C:O=12:32=3:8

Calcium oxide, (CAO)=Ca:O=40:16=5:2

Sodium CHLORIDE, (NaCl)=NaCl=23:35.5

Magnesium sulphide, (MgS)=24:32=3:4

Hence, the CORRECT match is option A.
