5 0
Answers:
(x+2) = 55 degrees

x = 53 degrees

the given is 72 degrees


Explanation:
A triangle always equals 180 degrees. It was given that one of the angle measures is 72 degrees. 180-72=108. Now I need to find the value of x. (x+2)+x=108. Solving this equation I get x=53. Substitute this back into the angle measures and u get the answers as stated above.

reflection symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in it
OlgaM077 [116]

Answer:

True if reflection over a line.

Step-by-step explanation:

Given that there is a reflection symmetry. We have to discuss about the quality of the design.

By reflection , we mean it can be either on a line or on a point.

If symmetry is on a line, then we get a mirror image of the original one keeping the line of symmetry as mirror.  Hence in this case when rotated about axis of symmetry lying it its plane the original design would be maintained.

Examples are : Circles, ellipses, hyperbolas, etc.

Reflection about a point is obtained by keeping equal distance form the point.

For example, reflection of (1,1) over origin would be (-1,-1)

Here the rotation quality may not apply

The diameter of the earth is about 7900 miles. The diameter of Jupiter is about 88,800 miles, approximately 11 times that of the
jeka94
<span>We know that the surface of a sphere is: S = 4 * pi * r^2 The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51 And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32 So the surface of Jupiter is around 11^2 times bigger than the Earth</span>

Suppose you want to draw a rectangle where the width is 7 inches less than the length and the diagonal is 2 inches longer than t
IrinaK [193]
The diagonal of a rectangle is:
 d ^ 2 = w ^ 2 + l ^ 2
 Where,
 w: width
 l: long
 Substituting values we have:
 (l + 2) ^ 2 = (l-7) ^ 2 + l ^ 2
 Rewriting we have:
 l ^ 2 + 4l + 4 = l ^ 2 -14l + 49 + l ^ 2
 l ^ 2 -14l + 49 - 4l - 4 = 0
 l ^ 2 -18l + 45 = 0
 (l-15) (l-3) = 0
 The solutions are:
 l = 15
 l = 3
 The viable solution is:
 l = 15
 Thus, the width is:
 w = l-7
 w = 15-7
 w = 8
 Answer:
 
the dimensions of the rectangle are:
 
l = 15
 w = 8
