Question

tan 70° 17' find the value of the following
​

Answer 1

Answer :

tan 70⁰ 17¹ = tan 70⁰12' + 5'

tan 70⁰ 12' = 2.7776

mean different SI = 0.0131

2.7776+0.0131 = 2.7907

tan 70⁰17' = 2.7907

hope it helps you..

Answer 2

Given :

• Tan 70° 17'

To find :

• The value

According to the question :

We have 17' which is not a factor of 6, so we can split it as ( 12' + 5' )

From the Table,

⟹ tan 70° 12'

⟹ tan 2.7776

Mean difference 5',

⟹ 2.7776 + 0131

⟹ 2.7907

Note : Refer the attachment for the table
