Answer:
17 units
Step-by-step explanation:
Because the triangle is isosceles, 2 of its sides are congruent; namely, the two sides that are opposite of the 2 congruent angles are contruent.
Because of the reason stated above, we can see that AC is congruent to BC, meaning that:
x+9=2x-8
-x -x
9=x-8
+8 +8
17 = x
Notice that BC is equal to x, so 17 is our final answer.
Answer:
74.32
Step-by-step explanation:
Add the two together, and you have your answer b/c it's asking for the total length of the line
Slope is how much a line goes up in ratio to how much the line goes to the right
(rise) / (run)
(y2 - y1) / (x2 - x1) when given points (x1, y1) and (x2, y2)
every time you go to the Right 1 unit, how much it goes Up is the slope
(if it is down, the slope is negative)
