24. A flat roof rises at a 30° angle from the front wall of a storage shed to the back wall. The front wall is

katovenus [111]

Answer:

Length of the roof line is $17.4\ feet$ . And depth of the shed is $15.07\ feet$

Step-by-step explanation:

Given front wall is 11.5 feet tall, back wall is 20.2 feet. And roof rises at 30° angle from the front wall.

Let $h$ be the length of the roof line. And $b$ the depth of the shed.

We can see it is a right angle triangle with opposite $20.2-11.5=8.7\ feet$ (see the attachment)

Now,

$sin(30)=\frac{Opposite}{Hypotenuse}\\ \\sin(30)=\frac{8.7}{h}\\\\h=\frac{8.7}{0.5}\\\\h=17.4\ feet$

Also,

$tan(30)=\frac{Opposite}{Adjacent}\\\\tan(30)=\frac{8.7}{b}\\\\b=\frac{8.7}{tan(30)}\\\\b=\frac{8.7}{0.577}\\\\b=15.07\ feet$

So, Length of the roof line is $17.4\ feet$ . And depth of the shed is $15.07\ feet$

Please help me, i will mark the brainliest pls!

Burka [1]

No because if you could use distributive property you would do 5*7 then 5*10 then you would get 35*50 which equals 1,750 and if you do it like it’s set up you would do 7*10 first cause PEMDAS so parentheses first so 7*10 is 70 then 70*5 is 350 and that’s not even close to the other answer so no you can’t .

What does the equation -9+|m-8|<0 equal to?

UNO [17]

The equation $-9+|m-8|$ equals to $-1 < m < 17$

Step-by-step explanation:

We need to solve the equation:

$-9+|m-8|$

Solving:

Adding 9 on both sides

$-9+9+|m-8|$

Applying absolute rule: |u| < a and a > 0 then, -a < u < a

So, $-9 < m-8 < 9$

Now we have,

m-8>-9 and m-8 <9

m>-9+8 and m <9+8

m>-1 and m<17

Combining the intervals:

-1 < m < 17

So the equation $-9+|m-8|$ equals to $-1 < m < 17$
