Let x be first num, x+2 be second, x+4 be third

x + 4(x+4) = 61
x + 4x + 16 = 61
5x = 45
x = 9

so 9, 11, 13

The explanation for this is one of my favorite pieces of mathematical reasoning. First, let's thing about distance; what's the shortest distance between two points? <em>A straight line</em>. If we just drew a straight line between A and B, though, we'd be missing a crucial element of the original problem: we also need to pass through a point on the line (the "river"). Here's where the mathemagic comes in.

If we take the point B and <em>reflect it over the line</em>, creating the point B' (see picture 1), we can draw a line straight from A to B' that passes through a point on the line. Notice the symmetry here; the distance from the intersection point to B' is<em> the same as its distance to B</em>. So, if we reflect that segment back up, we'll have a path to B, and because it came from of the line segment AB', we know that it's <em>the shortest possible distance that includes a point on the line</em>.

If we apply this same process to our picture, we see that the line segment AB' crosses the line \ell at the point (1, 1)

Can someone help please and thanks

Answer:

Step-by-step explanation:

Find the Supplement to 101

Supplementary angles = 180 degrees

180 = 101 + unknown                               Subtract 101 from 180

unknown = 79

Because the upper triangle is marked as having 2 equal sides, the left angle is also 79 degrees,

Now the vertex angle is 79 + 79 + y = 180   All triangles have 180 degrees

158 + y = 180                                                   Subtract 158 from both sides

y = 180 - 158

y = 22

y is vertically opposite the vertex angle of the lower triangle. Both the sides are marked as equal, so the angles opposite them are equal as well.

x + x + 22 = 180                                             Combine

2x + 22 = 180                                                 Subtract 22 from both sides.

2x = 180 - 22

2x = 158                                                          Divide by 2

x = 158/2

x = 79
