Answer:
XY = 17
Step-by-step explanation:
Intersect secant theorem, EX * EY = EZ*EW
34 * EY = 25.5 * 68
EY = 51
EX + XY = 51
34 + XY = 51
XY = 51 - 34 = 17
Answer:
Step-by-step explanation:
The total cost of the bench would be $72 after the markdown being 10% from the orginal proce which was $80.
Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = = 60
<span>The length of AC is 8 units
The angle CDB is 67°
Since ABCD is a rectangle, that means that all of the angles are 90 degrees and that line segment AB is parallel to line segment CD. The line segment BD is a diagonal of the rectangle. The line segment AC is also a diagonal of the rectangle so it has the same length as given for segment BD which is 8. The angle ABD is the angle between the horizontal line and the diagonal. The angle CDB is also the angle between a horizontal line and the diagonal. So it also has the same measurement so it too is 67°.</span>
