Find the measure of angle A

32.5

Step-by-step explanation:

The triangle with 50 in it has two equal angles so,

180 - 50 = 130

130/ 2 = 65

So the first triangle’s angles are

65, 65, 50

In the center we know 65 so

180 - 65 = 115

So we have one angle in the triangle with the angle we need to solve.

The triangle we are also solving is has two equal sides so

180 - 115 = 65

65/2 = 32.5

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
