Solve the equation if 0º≤x≤360º
tan x-1

45°, 225°

Step-by-step explanation:

Given that;

Tan x = 1

We can get Tan⁻¹ of 1

x =  Tan⁻¹ 1

x = 45

45° is the acute angle in the first quadrant

Tangent is positive in the 1st, and the 3rd quadrant.

Therefore in the third quadrant, x = 180 + 45 = 225

Hence; x = 45°  or 225°

Step-by-step explanation:

45 225 just took test

the discriminant is 64 + 4*1*12 = 112

this is prime.
