Answer:
cpctc and aas
Step-by-step explanation:
If u look at it there is only 2 angles and one side (aas) and cpctc because it saying that since we know it congruent then we know that ab is equal to cb
360 - 20 + 2x = 360
340 + 2x = 360
2x = 20
x = 10
5x + 9y = 0
to find the x int, sub in 0 for y and solve for x
5x + 9(0) = 0
5x = 0
x = 0
to find the y int, sub in 0 for x and solve for y
5(0) + 9y = 0
9y = 0
y = 0
the reason u cannot use just the intercepts is because the line goes through the origin (0,0)....The intercepts coincide giving u only 1 point...and that is not enough to graph a line
110+90+145=345
345 divided by 3=115
so the score of her third game was 145 points.
