Possible Answers:

A ray

An acute angle

An obtuse angle

Correct answer:

An obtuse angle

Explanation:

By definition, and obtuse angle is any angle that measure more than \(\displaystyle 90^\circ\), but less than \(\displaystyle 180^\circ\)

Ray

Possible Answers:

ray

line segment

angle

Correct answer:

ray

Explanation:

By definition, a ray starts at a point and continues in a certain direction, with no endpoint. 

Example Question #1054 : Common Core Math: Grade 4

The image below can be described as  ___________.

Angle

Possible Answers:

a line

an angle

a ray

Correct answer:

an angle

Explanation:

This image is an angle because it shows two rays meeting at an endpoint. 

Example Question #1051 : Common Core Math: Grade 4

The image below can be described as ___________.

Acute angle

Possible Answers:

a straight angle

an obtuse angle

an acute angle

Correct answer:

an acute angle

Explanation:

The image shows an acute angle because it has a measure of \(\displaystyle 46^\circ\), which is less than \(\displaystyle 90^\circ\)

Possible Answers:

a straight angle

a acute angle

an obtuse angle

Correct answer:

a straight angle

Explanation:

This image is a straight angle because it measures \(\displaystyle 180^\circ\).

Example Question #11 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

The image below can be described as ___________.

Right angle

Possible Answers:

an obtuse angle

an acute angle

a right angle

Correct answer:

a right angle

Explanation:

Example Question #823 : Operations

Solve for x. 

180 degrees

Possible Answers:

\(\displaystyle 95^\circ\)

\(\displaystyle 85^\circ\)

\(\displaystyle 90^\circ\)

\(\displaystyle 80^\circ\)

\(\displaystyle 100^\circ\)

Correct answer:

\(\displaystyle 90^\circ\)

Explanation:

The angle is a straight line. A straight line is \(\displaystyle 180^\circ\). To find the missing angle we subtract. 

\(\displaystyle 180-90=90\)
