b. is a number that stays fixed in an expression
c. the number in front of a variable
d. letters or symbols used in place of a quantity we do not know yet.

1. Exponents- e.is the number of times the BASE NUMBER is multiplied by itself.

2. Term- a.is a number by itself or the product of a number and variable (or more than one variable).

3. Variables- d.letters or symbols used in place of a quantity we do not know yet.

4. Coefficient- c.the number in front of a variable

5. Constant- b.is a number that stays fixed in an expression

Step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

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'.
