By looking at the problem, we can tell that 466 dollars is 2/3 of the original price. therefore, 1/3 of it would be 233 so the original price is 699
Answer:
<u>x = 120°, y = 20°</u>
Step-by-step explanation:
Let's recall that the four interior angles in any rhombus must have a sum of 360 degrees. In addition, the opposite interior angles must be equivalent, and the adjacent angles have a sum of 180 degrees.
∠ ABC and ∠ ADC are opposite interior angles, so they must have equivalent measurements, therefore x = 120 degrees.
To find the value of y, we use this equation because the interior angles of the Δ ADC add up to 180:
y = 180 - 120 - 40
y = 180 - 160
y = 20 degrees ⇒ z = 40 degrees
