​

Answer 1

Answer:

" FOLLOW " me plz

" BRAINLIEST " me plz

Explanation:

Tan(75°) = tan(45° + 30°)

Tan(75°) = tan(45° + 30°)

Tan(75°) = tan(45° + 30°) = [tan(45°) + tan(30°)]/[1 - tan(45°)tan(30°)]

Tan(75°) = tan(45° + 30°) = [tan(45°) + tan(30°)]/[1 - tan(45°)tan(30°)] = [1 + 1/√(3)]/(1 - 1/√(3)].

Tan(75°) = tan(45° + 30°) = [tan(45°) + tan(30°)]/[1 - tan(45°)tan(30°)] = [1 + 1/√(3)]/(1 - 1/√(3)].

Tan(75°) = tan(45° + 30°) = [tan(45°) + tan(30°)]/[1 - tan(45°)tan(30°)] = [1 + 1/√(3)]/(1 - 1/√(3)]. tan(75°) = (√(3) + 1)/(√(3) - 1).
