so uh i have a question about STEAM the app ik this is a math website but uh my question is lets say your playing roblox or mine
yawa3891 [41]

Answer:

Step-by-step explanation:

First off, steam isn't a math website.

On discord, it doesn't show steam specifically, but if you're playing a game THROUGH steam then yes, it will show.

To hide this, go to options -> game activity -> and disable "Display currently running game as a status message" on discord.

If you want to hide your status on steam, just put your status to invisible :)

A ladder 9.00 m long leans against the side of a building. if the ladder is inclined at an angle of 75.0° to the horizontal, wha
Anastaziya [24]

The question describes a right triangle with hypotenuse as 9 and one of the angles as 75 degrees. We are looking for the length of the leg adjacent the given angle 75 degrees.

Recall that:

\cos{\theta}=\cfrac{adj}{hyp}\\ \\ \Rightarrow\cos75^o=\cfrac{x}{9}\\ \\ \Rightarrow x=9\cos75^o=9(0.2588)=2.3 ft.

What is the value of x?
nikklg [1K]
It took me a minute, but I understand what it wants you to do.

a^2+b^2=c^2

Find the missing length on that one triangle to the left.

62^2+b^2= 99.2^2

Square the numbers. 

3844+b^2= 9840.64

Subtract 3844 on both sides. 

b^2= 5996.64 

Square root it. 

b= 77. 437975 round down to b= 77.4 

Now, we can find the length of the other missing side. (x+2)

77.4^2+b^2= 112^2

5990.76+b^2= 12,544

Subtract 5990.76 on both sides. 

b^2= 6553.24

Square root it. 

b= 80.952085, round to b=81

Now, plug that in. 

(x+2)= 81

Subtract 2 on both sides. 

x=79 (about)

I hope this helps! Make sure to check my work.
