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>
Answer:
no
Step-by-step explanation:
because a shape is rotational symmetrical when it looks the same after <em>any rotation</em> by partial turn.
A. Multiply the area of the original store by the percent increase then add that to the original amount.
1200 x 0.75 = 900
1200 + 900 = 2100
Answer: 2,100 square feet.
B. 2000 x 0.30 = 600
2000 + 600 = $2,600
2600 x 0.05 = 130
2600 + 130 = 2,730
Rent :$2,730
5.25 + 2.25 = 7.50 MB
x/100 x (7.50) = 5.25
7.50x/100 = 5.25
7.50x = 5.25(100)
7.50x = 525
x = 525/7.50
x = 70
Hence, 70% of the application has already been downloaded.
