Example Questions

Example Question #13 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

Solve for x. 

180 degrees

Possible Answers:

\(\displaystyle 100^\circ\)

\(\displaystyle 95^\circ\)

\(\displaystyle 80^\circ\)

\(\displaystyle 90^\circ\)

\(\displaystyle 85^\circ\)

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. 

\(\displaystyle 180-90=90\)

Example Question #14 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

Solve for x. 

150 degrees

Possible Answers:

\(\displaystyle 70^\circ\)

\(\displaystyle 40^\circ\)

\(\displaystyle 80^\circ\)

\(\displaystyle 60^\circ\)

\(\displaystyle 50^\circ\)

Correct answer:

\(\displaystyle 60^\circ\)

Explanation:

To find the value of x we subtract. 

\(\displaystyle 150-90=60\)

Example Question #1 : Recognize Angle Measure As Additive: Ccss.Math.Content.4.Md.C.7

Solve for x. 

65 degrees

Possible Answers:

\(\displaystyle 45^\circ\)

\(\displaystyle 50^\circ\)

\(\displaystyle 30^\circ\)

\(\displaystyle 40^\circ\)

\(\displaystyle 35^\circ\)

Correct answer:

\(\displaystyle 35^\circ\)

Explanation:

To find the value of x we subtract. 

\(\displaystyle 65-30=35\)

Example Question #1061 : Common Core Math: Grade 4

Solve for x. 

145degrees

Possible Answers:

\(\displaystyle 90^\circ\)

\(\displaystyle 85^\circ\)

\(\displaystyle 110^\circ\)

\(\displaystyle 100^\circ\)

\(\displaystyle 95^\circ\)

Correct answer:

\(\displaystyle 100^\circ\)

Explanation:

To find the value of x we subtract. 

\(\displaystyle 145-45=100\)

Example Question #826 : Operations

Solve for x. 

130degrees

Possible Answers:

\(\displaystyle 40^\circ\)

\(\displaystyle 45^\circ\)

\(\displaystyle 60^\circ\)

\(\displaystyle 55^\circ\)

\(\displaystyle 50^\circ\)

Correct answer:

\(\displaystyle 50^\circ\)

Explanation:

To find the value of x we subtract. 

\(\displaystyle 130-80=50\)

Example Question #12 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

Solve for x. 

45degrees

Possible Answers:

\(\displaystyle 30^\circ\)

\(\displaystyle 35^\circ\)

\(\displaystyle 50^\circ\)

\(\displaystyle 40^\circ\)

\(\displaystyle 45^\circ\)

Correct answer:

\(\displaystyle 45^\circ\)

Explanation:

Because of the square in the corner of the angle we have a \(\displaystyle 90^\circ\) angle. To find the missing piece of the angle we subtract. 

\(\displaystyle 90-45=45\)

Example Question #13 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

Solve for x. 

52degrees

Possible Answers:

\(\displaystyle 32^\circ\)

\(\displaystyle 36^\circ\)

\(\displaystyle 34^\circ\)

\(\displaystyle 30^\circ\)

\(\displaystyle 38^\circ\)

Correct answer:

\(\displaystyle 38^\circ\)

Explanation:

To solve for x we subtract. 

\(\displaystyle 90-52=38\)

Example Question #14 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

Solve for x. 

75degrees

Possible Answers:

\(\displaystyle 55^\circ\)

\(\displaystyle 40^\circ\)

\(\displaystyle 45^\circ\)

\(\displaystyle 60^\circ\)

\(\displaystyle 50^\circ\)

Correct answer:

\(\displaystyle 50^\circ\)

Explanation:

To solve for x we subtract. 

\(\displaystyle 75-25=50\)

Example Question #21 : Geometric Measurement: Understand Concepts Of Angle And Measure Angles

If we wanted to make this angle into a right angle, how many more degrees would we need to add? 

27degrees

Possible Answers:

\(\displaystyle 67^\circ\)

\(\displaystyle 65^\circ\)

\(\displaystyle 64^\circ\)

\(\displaystyle 66^\circ\)

\(\displaystyle 63^\circ\)

Correct answer:

\(\displaystyle 63^\circ\)

Explanation:

A right angle has a measurement of \(\displaystyle 90^\circ\). To find how much more we would need to add we subtract. 

\(\displaystyle 90-27=63\)

Example Question #121 : Measurement & Data

Solve for x. 

100degrees

Possible Answers:

\(\displaystyle 140^\circ\)

\(\displaystyle 120^\circ\)

\(\displaystyle 130^\circ\)

\(\displaystyle 100^\circ\)

\(\displaystyle 110^\circ\)

Correct answer:

\(\displaystyle 100^\circ\)

Explanation:

To find the value of x we add both of the known angles together. 

\(\displaystyle 40+60=100\)
