Question

The measure of angle is greater than 0° and less than 90°, then the angle is [ ] b) obtuse angle d) straight angle a) acute angle c) reflex angle d) straight angle​

Answer 1

`\large\boxed{\textsf{Option A. Acute Angle.}}`

Explanation:

`\textsf{We are asked what the angle is described as, given that it's greater than 0, and less than 90.}`

`\mathtt{Angle: 0 < x < 90.}`

`\large\underline{\textsf{Option A:}}`

`\textsf{An Acute Angle is any angle less than 90}^\circ}. \ \textsf{An Acute Angle is a good option to pick.}`

`\textsf{An Acute Angle \underline{matches} the given info. Option A is \underline{correct}.}`

`\large\underline{\textsf{Option B:}}`

`\textsf{An Obtuse Angle is an angle greater than 90}^(\circ), \ \textsf{but less than 180}^(\circ).`

`\textsf{This kind of angle doesn't match the given info. Option B is incorrect.}`

`\large\underline{\textsf{Option C:}}`

`\textsf{A Reflex Angle is any angle greater than 180}^(\circ), \ \textsf{but less than 360}^(\circ).`

`\textsf{This kind of angle clearly doesn't match the given info. Option C is incorrect.}`

`\large\underline{\textsf{Option D:}}`

`\textsf{A Straight Angle is equal to 180}^(\circ). \ \textsf{No more, and no less.}`

`\textsf{This kind of angle doesn't match the given info. Option D is incorrect.}`
