Answer:

  1. 109°, obtuse
  2. 131°, obtuse
  3. 53°, acute
  4. 124°, obtuse

Step-by-step explanation:

You are exected to know the relationships of angles created where a transversal crosses parallel lines.

  • Corresponding angles are equal (congruent).
  • Adjacent angles are supplementary, as are any linear pair.
  • Opposite interior (or exterior) angles are equal (congruent).

The appearance of the diagram often gives you a clue.

You also expected to know the name (or category) of angles less than, equal to, or greater than 90°. Respectively, these are <em>acute</em>, <em>right</em>, and <em>obtuse</em> angles.

1. Adjacent angles are supplementary. The supplement of the given angle is 109°, so x will be obtuse.

2. Opposite exterior angles are equal, so y will be 131°. It is obtuse.

3. Opposite interior angles are equal, so w will be 53°. It is acute.

4. Corresponding angles are equal, so x will be 124°. It is obtuse.

Find the value of x for which 2x ^(1/ 2) = 32.
Mrac [35]

Answer:

The value of x will be 8    

Step-by-step explanation:

We have given that 2\sqrt{x}=32

We have to find the value of x

As 2\sqrt{x}=32

For finding the value of x we have to square both side

On squaring both side

We done squaring both side for easy simplification

4x=32

So x = 8

So the value of x will be 8

So answer will be 8
