Answer:

60 units^2

Step-by-step explanation:

In order to find the area of a triangle, you do baseXheight/2. However, we don't have the height. So, we use the pythagorean theorem to solve for the missing side.

8^2+x^2=17^2

64+x^2=289

x^2=225

x=15

So, now we can solve for the area.

15*8=120

And divide by 2 we get 60

Answer:

$c)\overline{AC}=2\overline{AB}$

Step-by-step explanation:

<u>Retrieved Information:</u>

Which statement is not true?

a) $a)\overline{AC}=\overline{CB}\\b)\overline{CB}=\frac{1}{2}\overline{AB} \\c)\overline{AC}=2\overline{AB}\\d)\overline{AC}+\overline{CB}=\overline{AB}$

b) Check the graph below

1) To bisect is to equally divide an angle or a line segment, into two equal parts. The bisector of AC divides the line segment AC in its midpoint, so AC≅CB, therefore AC=CB. In addition to this, this is equivalent to say that CB is = 1/2AB.

Finally, this is also true that AC+CB=AB.

2) Clearly AC is not equal to 2AB since AC=CB is = 1/2AB then it is false.

$c)\overline{AC}=2\overline{AB}\:FALSE$
