Question

Find tan-1 1.4281 to the nearest degree.
a. 10°
b. 55°
C. 5°
d. 35°

Answer 1

`\:x=55^(\circ \:\:)`

Therefore, option 'b' is correct.

Explanation:

Let x be the angle

• tan x = 1.4281

determining the
`\tan ^(-1)\left(1.4281\:\right)`

`\:\tan \:x\:=1.4281\:`

`x=\tan ^(-1)\left(1.4281\:\right)`

`\:x=55^(\circ \:\:)`

Therefore, option 'b' is correct.
