Answer:




Step-by-step explanation:
Given:

bisects angle BAC

Triangle ABC is isosceles triangle, because
Angles adjacent to the base of isosceles triangle ABC are congruent.
Hence,

The sum of the measures of all interior angles is 180°, so,

Since
bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,

AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,

This is what you would do
120 x 17= 2040
Or you could do 12 x 17 then, add a zero to the end of it.
Then you would divid from what you got when you did 120 x 17 by 60
That should give you the answer.
Hope this helps if im not mistaken it should be 34
2040 <span>60 </span>= 34
34 = 340 to the nearest tenth
34 = 34 to the nearest hundredth
34 = 34 to the nearest thousandth
= 0 to the nearest tenth
= 0 to the nearest hundredth
= 0 to the nearest thousandth
A. because your x= 0, 1, and -5
147 is not a prime number 147= 49 * 3
49 is divisable by 7: 49= 7 * 7
7 is not divisable by anything
