The answer would be 53. This can be found by add 127 twice (xy and uz) and subtracting it from 360. This would give you 106 and you would divide it by 2 for the 2 angles left and get the answer.

Find the distance between the points (1, 7) and (10, 1) Please help:)

klio [65]

Answer:

The distance between the points (1, 7) and (10, 1) is 10.82 units

Step-by-step explanation:

Distance between two points

The distance between points A(x,y) B(w,z) can be calculated with the formula:

$d=\sqrt{(z-y)^2+(w-x)^2}$

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

$d=\sqrt{(1-7)^2+(10-1)^2}$

$d=\sqrt{(-6)^2+(9)^2}$

$d=\sqrt{36+81}=\sqrt{117}\approx 10.82$

The distance between the points (1, 7) and (10, 1) is 10.82 units

1-2 sin e cos 20-2 sin 40 = cos (20)

natka813 [3]

Answer:

No this is not the same as cos(2Ф)

Step-by-step explanation:

First I changed the $cos^{2}$ Ф into 1- $sin^{2}$ Ф

I then foiled the (1-2 $sin^{2}$ Ф)(1- $sin^{2}$ Ф) and that resulted in 1- $sin^{2}$ Ф-2 $sin^{2}$ Ф+2 $sin^{4}$ Ф

From there, I then cancelled the two 2 $sin^{4}$ Ф and combined like terms and was left with 1-3 $sin^{2}$ Ф

Now 1-3 $sin^{2}$ Ф ≠ cos(2Ф)
