- ∠W is a right angle.
<h3>Properties of a Square.</h3>
- All sides are equal to each other.
- Opposite sides are parallel to each other.
- All the angles are right angle.
- The diagonals bisect each other and are perpendicular.
Therefore, the statement that must be true about square WXYZ are as follows;
- WX ≅ XY
- WX ≅ YZ

Where is this triangle you speak of
Answer:
(b) 21.4
Step-by-step explanation:
There are a couple of interesting relations regarding chords and secants and tangents of a circle. With the right point of view, they can be viewed as variations of the same relation, possibly making them easier to remember.
When chords cross inside a circle (as here), each divides the other into two parts. The product of the lengths of the two parts of one chord is the same as the product of the lengths of the two parts of the other chord.
Here, that means ...
7x = 10·15
x = 150/7 = 21 3/7 ≈ 21.4

<em>Additional comment</em>
A secant is a line that intersects a circle in two places. (A tangent is a special case of secant where the two points of intersection are the same point.) When two secants meet outside the circle, there is a special relation between the lengths of the various line segments.
Consider the line segment from the point where the secants meet each other to the far intersection point with the circle. The product of that length and the length to the near intersection point with the circle is the same for both secants.
Here's the viewpoint that merges these two relations:
<em>The product of the lengths from the point of intersection of the lines with each other to the two points of intersection with the circle is the same for each line</em>.
(Note that when the "secant" is a tangent, that product is the square of the distance from the tangent point to the point of intersection with the other line--the distance to the circle multiplied by itself.)
It could not be 73º because if you add that to 120 then it will be more than 180 degrees, which is the total number of degrees in a triangle. Hope this helps!
Answer:
28 and 6
Step-by-step explanation:
List the factors (excluding itself):
6: 1, 2, 3,
28: 1, 2, 4, 7, 14
Add them up!
1+2+3=6
1+2+4+7+14=28
if they add up to the original number then the number is perfect.
