Step-by-step explanation:
In a rectangle
• All angles are right angles
• the diagonals are congruent
In Δ WXV the sum of the 3 angles = 180°
∠ WXZ = ∠ XWY =
=
= 58°
∠ YXZ = 90° - 58° = 32°
∠ WVZ = 180° - 64° = 116° ( adjacent angles are supplementary )
∠ XWZ = 90° ( by definition of rectangle )
∠ XZY = ∠ WXZ = 58° ( corresponding angles )
The "horizontal" distance is 8-2 = 6.
The "vertical" distance is 7-3 = 4.
The Pythagorean theorem tells you the straight line distance is then
√(6² + 4²) = √52 = 2√13 ≈ 7.21
Answer:
Option C is correct.
The expression represents the number of stamps Erykah has : 3r -6
Step-by-step explanation:
Let r be the number of stamps Chris has.
as per the given condition: Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his.
"3 times the number of stamps Chris has" means 3r
"6 less than 3 times number of stamps Chris has" which means subtract 6 from 3r i,e 3r -6
therefore, the expression 3r -6 represents the number of stamps Erykah has.
