Question

Find tan^-1 1.4826 to the nearest degree

Answer 1

A= 131 degrees 3 min or

A = 311 deg 3 min

Explanation:

Given is a value -1.14826

We have to find the angle such that

tan A= -1.14826

We know that tangent is negative in II and IV quadrant.

Hence angle A should lie in II or IV quadrant.

First find B such that

tan B =1.14826(removing negative sign)

`B=48.95 =48 degree 57 min`

Hence
`A =180-B : A=360-BA=131.05 : A=311.05\\`

Answer 2

answer is 56.00 degree
