We know that
in a right triangle
cos θ=adjacent side angle <span>θ/hypotenuse
in this problem

</span>adjacent side angle θ=38 in
hypotenuse=40 in

cos θ=38/40
θ=arc cos (38/40)-------> 18.19°-------> 18°

the answer is
18 degrees

Answer:

The wheels have to rotate 500 times

Step-by-step explanation:

The wheel is 1 meter in diameter so we need to find the circumference.

C = 2\pir

C = 2\pi1

C= 2\pi

2meters = .002kilometers

1000meters = 1kilometer

1000/2 = 500

Someone please help me on this math problem!
Galina-37 [17]

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19       <em>add 29 to both sides</em>

10y = 7y + 48          <em>subtract 7y from both sides</em>

3y = 48      <em>divide both sides by 3</em>

y = 16



3x + 7 = 5x - 21            <em>subtract 7 from both sides</em>

3x = 5x = -28         <em>subtract 5x from both sides</em>

-2x = -28     <em>divide both sides by (-2)</em>

x = 14

50% of the surface area of a piece of bread is crust what is the height
andrezito [222]
The formula for surface area is SA = 2 (wl + hl + hw). Plugging in the numbers that we know, we get SA = 2 (100 + 10h +10h). We know that the crust accounts for half of the surface area.

The surface area was not provided so this is the closest I can go without the provided surface area. I hope this helps you :)

A(-5,-4) ——&gt; A’ is a glide reflection where the translation is (x,y)—-&gt;(x+6,y), and the line of reflection is y=3. What ar
Nastasia [14]

Solution:

The Point in the coordinate plane is A(-5,-4).

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

=\sqrt{(-5+5)^2+(3+4)^2}\\\\=7

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

Option C: (1,10) is the glide reflection of point A(-5,-4).
