1. 5,000 times 1.09 times 5 = 2,693
2. 5,000 - 6,500= 1500 ÷4 = 3.3%
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 formula for the area of a square is A = s^2, where s is the side length. Here, 225 cm^2 = s^2.
To find the side length, we need only take the sqrt of both sides of this equation and eliminate the negative root:
plus or minus √{225 cm^2) = s. Thus, s = 15 cm = side length.
