at a) paint the figure horizontal on the right side. P becomes P´
b) paint the figure A one step clochwise arround P. 60° is one angle of the triangles. All angles in a triangle are together 180°. so we have 3 angles with same size so 180°/3=60°
c) go two triangles to the left and paint the same figure A as on the left side of l.
Answer:
cot α = 1/tan α = 1/2.4 = 0.42
Step-by-step explanation:
cot α=0.42
sin α = 0.92
we know that cot α = 1/tan α
thus,
cot α = 1/tan α = 1/2.4 = 0.42
we know that
sin(x)=tan(x)1+tan2(x)√
![\ sin(\alpha )=tan(\alpha )/\sqrt{ 1+tan^2(\alpha )} \\sin(\alpha )= 2.4/\sqrt{1+2.4^2} = 2.4/\sqrt{1+5.76}\\sin(\alpha )= 2.4/\sqrt{6.76} = 2.4/2.6 = 12/13 = 0.92](https://tex.z-dn.net/?f=%5C%20sin%28%5Calpha%20%29%3Dtan%28%5Calpha%20%29%2F%5Csqrt%7B%201%2Btan%5E2%28%5Calpha%20%29%7D%20%5C%5Csin%28%5Calpha%20%29%3D%202.4%2F%5Csqrt%7B1%2B2.4%5E2%7D%20%20%3D%202.4%2F%5Csqrt%7B1%2B5.76%7D%5C%5Csin%28%5Calpha%20%29%3D%202.4%2F%5Csqrt%7B6.76%7D%20%3D%202.4%2F2.6%20%3D%2012%2F13%20%3D%200.92)
sin α = 0.92
Answer is 1.538
Using (x1,y1)(x2,y2)
x1=0
Y1=2
X2=5.2
Y2=10
Using the equation given, F = 15 + 32 which equals 47, so I don't see how any of the choices are accurate, but if I had used the proper equation, I would get 59 Farenheit or answer D!
