Answer:
<em>160°</em>
<em />
Step-by-step explanation:
We can use the central angle theorem for this. It says that an angle inscribed in a circle (on the circumference) measured half of the arc it intercepts (by 2 points on the circumference of the circle).
<em>that would mean that Angle KAW is </em><em>half </em><em>of measure of Arc KW.</em> Thus we can write:
m∠A = 0.5 (arc KE + arc EW)
x+45 =0.5 (x+20+3x)
x+45 = 0.5(4x+20)
x+45 = 2x + 10
45 - 10 = 2x - x
Thus, x = 35
<em>Since Arc KW = Arc KE + Arc EW and x = 35, we can say:</em>
<em>Arc KW = x + 20 + 3x = 35 + 20 + 3(35) = 160°</em>
The answer must be - cospi/2 which is not available in the option
Answer:
<u>answer is C ( </u>
<u> )</u>
Step-by-step explanation:
so here is how you do it.
first you need to find out what 
is
which is the same as 3 X 3 X 3 X 3 X 3 X 3 X 3 X 3
the answer to that is 6,561
then you have to square root that
which looks like this
which is 81
which means that you have to find the same expression that equals to 81
I then did (C) to see if the answer will be 81 and it is. so your answer is C
