the one that you selected is correct
Step-by-step explanation:
polygons cannot have a curve in them therefore the first one is correct
1. A = ¹/₂bh
26 = ¹/₂(8)(h)
26 = ¹/₂(8h)
26 = 4h
4 4
6¹/₂ = h
The answer is D.
2. The answer is C.
Using the identity cos(2x) = 2 cos^2x - 1
18 + 9(2 cos^2 x - 1) = 27 cos x
18cos^2 x - 27 cos x + 9 = 0
2 cos^ x - 3 cos x + 1 = 0
(2 cos x - 1 )(cos x - 1 ) = 0
cos x = 1/2 , 1
x = pi/3, 5pi/3, 0, 2pi answer
<span>Scott read 4. Put it this way: x=4. If = 4, then put it into an equation. 5x-3= 17. So, you add three to both sides, then it comes out as this: 5x= 20. Divide by five, and you get x= 4.</span>
