Answer:
Step-by-step explanation:
According to Pythagoras Theorem a² + b² = c²
And the questio is having a right triangle in it so,
(Height of the building)² + (Length of the shadow)² = (The distance from the top of the building to the tip of the shadow)²
⇒ a² + (12)² = (20)²
⇒ a² = (20)² - (12)²
⇒ a² = 400 - 144
⇒ a² = 256
⇒ a = √256
⇒ a = 16
Answer:
They are equidistant from origin.
Step-by-step explanation:
Rectangle LMNO is rotated 90° clockwise around the origin to create rectangle L'M'N'O'. Which statement would best describe the relationship between points N and N'?
They are equidistant from origin.
They are midpoints of segment ON and segment O prime N prime.
They are equidistant from point O.
They are midpoints of segment LN and segment L prime N prime.
Answer: If a point with location N(x, y) is rotated 90° clockwise around the origin, the new coordinate N' is at (y, -x). The distance of the two points from the origin O(0, 0) can be calculated using:

Therefore ON = ON'. The points N and N'are equidistant from the orign
