Answer:

6.519801752°

Step-by-step explanation:

Let θ represent the angle of depression

tanθ=40/350

θ=tan^-1(40/350) *tan^-1 means inverse tan*

θ=6.519801752°

Answer:

12.

Square root = 37,

Step-by-step explanation:

40^2 = 1600

35^2 = 30 * 40 + 25 = 1225

So the requred square is between 35 and 40

38^2 = 1444

37^2 = 1369 - so its this one.

Required difference = 1381 - 1369 = 12.

This is stupid I know lol but I'm having a hard time remembering the difference between a histogram and a bar graph. Can someone
Y_Kistochka [10]

<u>In Bar Graphs;</u>

- Bars have equal space

- One the y-axis, we have numbers & on the x-axis, we have data which can be anything.

<u> In Histograms;</u>

- Bars are fixed

- On the y-axis, we have numbers & and on the x-axis, we have data which in continuous & will always be number.

<u>An easy way you can remember the difference is looking at the spaces of the bars. </u>

<em>A bar graph has gaps</em>

<em>A histogram has no gaps.</em>

Please help! Thank you so much!

Angle W:

180 = 90 + 57 + W

180 = 147 + W

W = 33 degrees

Using trigonometry functions to find the side lengths. (SOH CAH TOA)

Side XZ:

cos(57) = XZ / 18

XZ = cos(57) x 18

XZ = 9.8 units

Side XW:

sin(57) = XW / 18

XW = sin(57) x 18

XW = 15.1 units

Hope this helps!! :)
