Question 1 of 5
1. Question
Find the value of `b`
- `b=` (31)`°`
Correct
Fantastic!
Incorrect
Alternate Angles
Corresponding Angles
Co-Interior Angles
Alternate Angles are equal.We can see from the diagram that `31°` and `b` are alternate angles, which means they are equal
Therefore, `/_ b=31°``/_ b=31°` -
Question 2 of 5
2. Question
Find the value of `x`
- `x=` (111)`°`
Correct
Nice Job!
Incorrect
Alternate Angles
Corresponding Angles
Co-Interior Angles
Corresponding Angles are equal.We can see from the diagram that `111°` and `x` are corresponding angles, which means they are equal
Therefore, `/_ x=111°``/_ x=111°` -
Question 3 of 5
3. Question
Find the value of `x`
- `x=` (89)`°`
Correct
Fantastic!
Incorrect
Alternate Angles
Corresponding Angles
Co-Interior Angles
Corresponding Angles are equal.We can see from the diagram that `89°` and `x` are corresponding angles, which means they are equal
Therefore, `/_ x=89°``/_ x=89°` -
Question 4 of 5
4. Question
Find the value of `y`
- `y=` (84)`°`
Correct
Correct!
Incorrect
Vertically Opposite Angles
Corresponding Angles
Co-Interior Angles
Corresponding Angles are equal.Vertically Opposite Angles are equal.Let the angle corresponding to of `84°` be `x`. Notice that `x` is vertically-opposite to `y`.First, we can see from the diagram that `84°` and `x` are corresponding angles, which means they are equal
Therefore, `/_ x=84°`Finally, we can see that angle `x` is vertically opposite to angle `y`
Since vertically opposite angles are equal, `/_ y=84°``/_ y=84°` -
Question 5 of 5
5. Question
Find the value of `x`
- `x=` (50)`°`
Correct
Great Work!
Incorrect
Alternate Angles
Corresponding Angles
Co-Interior Angles
Co-Interior Angles are when two angles have a sum of `180°`.To solve for `x`, add it to `130°` and set their sum to `180°`.We can see from the diagram that `130°` and `x` are co-interior angles, which add up to `180°`
Since co-interior angles add to `180°,` add the angle measures and set their sum to `180°.` Then, solve for the value of `x`.`x+130` `=` `180` `x+130` `-130` `=` `180` `-130` Subtract `130` from both sides `x` `=` `50°` `/_ x=50°`
