Point w is at (-4,0) and z is at (0,-5). the segment WZ is one side of the square. the distance from W to Z is√(-4²+5²)=√41. the perimeter is then 4√41 or approx 25.6
Answer:
200
Step-by-step explanation:
-625 + 925 = 300
300 +100 = 400
400 +(-200) = 400-200
400-200 = 200
Answer:
79 degrees
Step-by-step explanation:
This is because <CBF is equivalent to <GFI
So, we know two angles in that triangle; 55 and 46.
By adding these together we get 101. In a triangle, the angles all add up to 180.
So we must subtract 101 from 180 and we will have that remaining angle.
Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
