Answer:
∠ACB= 57°
AB= 8.80 units (3 s.f.)
AC= 10.1 units (3 s.f.)
Step-by-step explanation:
Please see attached picture for full solution.
From left to right, the answers are: 152, D(line e), C(obtuse), 44 degrees.
Now I feel guilty and sleezy. Giving answers alone without explanations
is something I almost never do, because it doesn't help anybody do
anything but cheat. But it's all I have time for right now. If a mod comes
along and decides to delete this because of no explanations, then let him
delete it. It'll serve us right, you and me both.
Refer to the attached image.
As we can observe ABCD is a square, whose corners that is A,B,C and D lie on the circle.
The diameter AC = 0.35 meter.
We have to find the side of square.
Let the measure of side of a square be 'l' meter
In triangle ABC,
By Pythagoras theorem, we get
So, l = 0.25 meter
Therefore, the measure of side of the square is 0.25 meter.
