Answer:

  • ∠x = 80°
  • ∠y = 40°
  • ∠z = 60°

Step-by-step explanation:

The angle marked x and the one marked 100° form a linear pair, so are supplementary. The measure of x is ...

  x = 180° -100° = 80°

__

The angle marked 40° and the one marked y are "alternate interior angles" with respect to the parallel lines and the diagonal that crosses them. As such, they have the same measure:

  y = 40°

__

The angle marked 100° and the sum of angles in the lower right corner are "corresponding" angles, so have the same measure. That is ...

  100° = 40° +z

  z = 100° -40° = 60°

Find the measure of ∠3.
Shkiper50 [21]

This is a kite due to the adjacent congruent sides (shown by the tickmarks). With any kite, the diagonals are perpendicular. So angle 3 is 90 degrees.

<h3>Answer: 90 degrees</h3>

Answer:

7.2% increase (rounded up to the nearest tenth of a percent)

Step-by-step explanation:

The price of the notebook today is $3.70

The price of the same notebook (original price) yesterday was $3.45

Increase in price = $3.70 - $3.45 = $0.25

Percentage increase = (Increase ÷ original price) × 100

Percentage increase = \frac{0.25}{3.45} × 100 = 7.2% (rounded up to the nearest tenth of a percent)
