Question

A
75°
B.
Reflex Angle B =
degrees.

Answer 1

285

Explanation:

B+A=360, B=360-75=285

Answer 2

An angle whose measure is greater than 180° but less than 360° is termed a reflex angle.

`\large{\textrm{{{\color{navy}{∠A \: + \: ∠B \: = \: 360°}}}}}`

`\bf \large \longrightarrow \: \:75 \degree \: + \: ∠ B \: = \: 360°`

`\bf \large \longrightarrow \: \: \angle B \: = \: 360° \: - \: 75 \degree`

`\bf \large \longrightarrow \: \: \angle B \: = \:285 \degree`
